Quick Answer

When sponsoring a family member for a green card in San Diego, you must prove you can financially support them. The Affidavit of Support (Form I-864) is a legally binding contract between you and the U.S. government that remains enforceable for years. San Diego's high cost of living — with median rents exceeding $2,400 per month and a cost of living index 44% above the national average — makes understanding income requirements and asset calculations especially important for sponsors in this region.

When sponsoring a family member for a green card in San Diego, you must prove you can financially support them. The Affidavit of Support (Form I-864) is a legally binding contract between you and the U.S. government that remains enforceable for years. San Diego's high cost of living — with median rents exceeding $2,400 per month and a cost of living index 44% above the national average — makes understanding income requirements and asset calculations especially important for sponsors in this region.

What is the Affidavit of Support?

Form I-864 is a legal document where you promise to financially support the immigrant you are sponsoring at 125% of the federal poverty level. This is not a formality — it is a legally enforceable contract. The U.S. government and the sponsored immigrant can both sue you to enforce this obligation if the immigrant receives means-tested public benefits like Medicaid, SNAP (food stamps), or SSI.

The obligation created by the I-864 lasts until one of five events occurs: the immigrant becomes a U.S. citizen, the immigrant earns 40 qualifying quarters of work (approximately 10 years of employment), the immigrant permanently leaves the United States, the immigrant dies, or the sponsor dies. Divorce does not end the obligation — even if you divorce the person you sponsored, you remain financially responsible until one of the five triggering events occurs.

USCIS takes the I-864 extremely seriously. According to USCIS data, approximately 15% of family-based green card applications receive Requests for Evidence (RFEs) related to the Affidavit of Support, making it one of the top reasons for processing delays. Common issues include insufficient income documentation, incorrect household size calculations, and failure to include all required tax documents.

2025 Income Requirements

The federal poverty guidelines are updated annually, and 2025 requirements for sponsors in the 48 contiguous states (including California) are shown below. You must demonstrate income at 125% of the poverty level for your total household size, which includes yourself, your dependents, and the immigrant(s) you are sponsoring.

How to Calculate Your Household Size

One of the most common errors on the I-864 is incorrectly calculating household size. Your household size includes every person who will depend on your income for support, regardless of whether they live with you. You must count the following people:

First, count yourself — you are always included. Second, count all dependents listed on your most recent tax return, including children, elderly parents, or anyone else you claim. Third, count the immigrant(s) you are currently sponsoring with this I-864. Fourth, count any other immigrants you previously sponsored who still have your active I-864 obligation. Fifth, count any other people living with you who depend on you for more than 50% of their financial support.

For example, if you are a married father with two children sponsoring your mother, your household size is 5: yourself, your spouse (tax dependent), two children (tax dependents), and your mother (the sponsored immigrant). If you previously sponsored your brother and he has not yet become a citizen or earned 40 work quarters, add him too — making your household size 6.

What Counts as Income?

USCIS considers your gross annual income from your most recent federal tax return as the primary measure of your financial ability. The following income sources all qualify:
  • Salary and wages from employment (W-2 income)
  • Self-employment income (Schedule C, net profit)
  • Rental income from investment properties (Schedule E)
  • Social Security retirement or disability benefits
  • Pension and retirement account distributions
  • Alimony and child support payments you receive (if consistent and court-ordered)
  • Interest and dividend income from investments
  • Spouse's income — if your spouse is willing to sign Form I-864A as a household member

What if You Do Not Meet the Income Requirement?

If your income falls below the required threshold, you have three options to bridge the gap. Each option has specific rules and documentation requirements.

Option 1: Count Assets. You can supplement your income by demonstrating sufficient assets. The value of countable assets must equal at least three times the difference between your income and the required income level. For siblings and parents of U.S. citizens, the multiplier increases to five times the difference. Countable assets include bank accounts (savings and checking), stocks, bonds, and mutual funds, certificates of deposit, real estate equity (appraised value minus mortgage balance), and the cash value of life insurance policies. Personal property like cars and furniture generally does not count.

Option 2: Use a Joint Sponsor. Any U.S. citizen or lawful permanent resident who meets the income requirement independently can serve as a joint sponsor. The joint sponsor files a separate I-864 and takes on the same legally binding obligation as the petitioning sponsor. The joint sponsor does not need to be related to you or the immigrant. In San Diego, where many Arab families have extended community networks, finding a joint sponsor through the local mosque, church, or community organization is common.

Option 3: Include Household Members. Other adults living in your household who contribute income can sign Form I-864A to combine their income with yours. This only works if they are willing to accept legal responsibility for supporting the immigrant.

Required Documents for the I-864

Incomplete documentation is the number one reason I-864s are rejected. Gather all of the following documents before filing:
  • Completed Form I-864 (18 pages, signed and dated)
  • Copy of your most recent federal tax return (Form 1040) with all schedules
  • All W-2s and 1099s from the most recent tax year
  • Three years of tax returns if self-employed or if income fluctuates significantly
  • Current employment verification letter stating your job title, hire date, and annual salary
  • Three most recent pay stubs showing year-to-date earnings
  • Proof of U.S. citizenship or permanent residence (passport, naturalization certificate, or green card)
  • Evidence of relationship to the immigrant (marriage certificate, birth certificate)
  • Proof of assets with current valuations (if using assets to supplement income)
  • Form I-864A signed by any household member contributing income
  • Joint sponsor's complete I-864 package with all supporting documents (if applicable)

Special Considerations for San Diego Sponsors

San Diego presents unique challenges for I-864 sponsors. The city's cost of living ranks among the highest in California, with the median home price exceeding $875,000 and average rents for a two-bedroom apartment at $2,600 per month. While the I-864 income requirements are based on federal poverty guidelines (which are the same nationwide except for Alaska and Hawaii), USCIS officers conducting interviews at the San Diego Field Office do consider local cost of living when evaluating the overall credibility of a sponsor's financial ability.

For Arab families in San Diego — particularly in neighborhoods like City Heights, El Cajon, and National City where many Arabic-speaking immigrants live — we frequently see situations where sponsors work in cash-heavy businesses like restaurants, convenience stores, and taxi services. If your tax returns do not fully reflect your actual income because of cash transactions, you need to start reporting all income on your tax returns at least one year before filing the I-864. Amended tax returns are accepted but receive additional scrutiny.

Self-employed sponsors face particular challenges because USCIS uses net self-employment income (after business deductions) rather than gross revenue. Many small business owners take significant deductions that reduce their taxable income below the I-864 threshold. If you are self-employed and planning to sponsor a family member, consult with both a tax professional and an immigration specialist at least one year in advance to optimize your tax strategy while meeting sponsorship requirements.

Common Mistakes That Delay Your Case

Based on our experience processing hundreds of I-864 forms for San Diego families, these are the most frequent errors that trigger RFEs and delays:

First, using the wrong tax year. USCIS requires your most recent tax return. If you file your I-864 in March 2026 but your 2025 taxes are not yet filed, you must use your 2024 return and include a letter explaining that 2025 taxes have not been filed yet. Do not leave the tax return section blank.

Second, forgetting to sign the form. Every I-864 must be signed in wet ink (blue or black pen). Digital signatures are not accepted. Both the sponsor and any household members filing I-864A must provide original signatures.

Third, incorrect household size. As explained above, your household size includes people you may not think of — previous sponsored immigrants, dependents who do not live with you, and the immigrant being sponsored. Undercounting makes it appear you meet the income threshold when you do not.

Fourth, not including all pages of tax returns. USCIS wants complete tax returns including all schedules. Missing Schedule C (self-employment), Schedule E (rental income), or Schedule D (capital gains) triggers an automatic RFE.

FAQFrequently Asked Questions

Q:How long am I financially responsible?

A: Until the immigrant becomes a U.S. citizen, earns 40 qualifying work quarters (approximately 10 years of employment), permanently leaves the U.S., or dies. Divorce does not end the obligation.

Q:Can a joint sponsor help?

A: Yes, any U.S. citizen or permanent resident who independently meets the income requirement for their own household size plus the sponsored immigrant can serve as a joint sponsor. They file a separate I-864 and accept full legal responsibility.

Q:What if I lose my job after filing?

A: Your legal obligation continues regardless of your employment status. The government and the sponsored immigrant can require you to reimburse any means-tested public benefits the immigrant receives. This is why the I-864 is called a legally binding contract.

Q:Can I use cryptocurrency or retirement accounts as assets?

A: Retirement accounts (401k, IRA) count as assets but only at their current cash value minus any early withdrawal penalties. Cryptocurrency is more complex — USCIS has no official policy, but documented holdings on established exchanges with verifiable market value have been accepted in some cases.

Q:What happens at the I-864 interview?

A: At the San Diego USCIS Field Office, the officer reviews your I-864 and may ask about your employment, income sources, and ability to support the immigrant. Bring original tax returns, recent pay stubs, and a current employment letter. The interview typically takes 15-30 minutes.

Q:Do I need the I-864 for every family member I sponsor?

A: Yes, a separate I-864 is required for each immigrant you sponsor. If you are sponsoring a spouse and two children simultaneously, you file one I-864 listing all three as immigrants, but the household size calculation includes all of them.

Q:What if my income is just barely above the threshold?

A: If your income is close to the minimum, include additional evidence of financial stability: savings account statements, property ownership documents, and a letter from your employer confirming continued employment. Borderline cases receive extra scrutiny.
