Quick Answer

The K-2 visa is a derivative visa that allows unmarried children under 21 of K-1 fiancé visa holders to enter the United States alongside their parent. USCIS processes over 35,000 K-1 petitions annually, and approximately 15% include K-2 derivative children. K-2 beneficiaries must be listed on the parent's I-129F petition, attend their own consular interview, and adjust status to lawful permanent resident within 90 days of the parent's marriage to the U.S. citizen petitioner. SoCal Immigration Services in Anaheim guides families through every step of the K-2 visa process.

Anaheim is one of Orange County's largest and most diverse cities, home to a thriving immigrant community that includes families from the Middle East, Latin America, Southeast Asia, and beyond. Many U.S. citizens in Anaheim are engaged to foreign nationals who have children from previous relationships, making the K-2 visa an essential part of their family reunification plan. The K-1 fiancé visa allows the foreign fiancé to enter the United States, but without the K-2 derivative visa, their minor children would be left behind. SoCal Immigration Services provides comprehensive K-1 and K-2 visa services for families throughout Anaheim, Garden Grove, Fullerton, and Orange County, ensuring that no child is separated from their parent during the immigration process.

What Is the K-2 Visa?

The K-2 visa is a derivative nonimmigrant visa available to the unmarried children under 21 years of age of K-1 fiancé visa holders. When a U.S. citizen files an I-129F Petition for Alien Fiancé on behalf of their foreign fiancé, the petition can also include the fiancé's minor children as K-2 beneficiaries. The K-2 visa allows these children to accompany or follow to join their K-1 parent in the United States. USCIS processes over 35,000 K-1 fiancé petitions each year, and approximately 15% of those petitions include one or more K-2 derivative children — representing thousands of families who rely on this visa category to stay together during immigration.
  • The K-2 visa is a derivative of the K-1 fiancé visa — it exists only because of the parent's K-1 status and cannot be filed independently
  • Only unmarried children under 21 years of age at the time of visa issuance qualify for K-2 classification
  • Children must be the biological or legally adopted children of the K-1 visa holder (not the U.S. citizen petitioner)
  • K-2 children can enter the United States at the same time as the K-1 parent or follow to join within one year of the K-1 visa issuance date
  • There is no separate petition fee for K-2 beneficiaries — they are included on the parent's I-129F petition
  • Each K-2 child must attend their own consular interview and undergo medical examination

K-2 Visa Eligibility Requirements

K-2 visa eligibility is determined by the child's relationship to the K-1 visa holder, the child's age, and the child's marital status. Meeting all three requirements is mandatory for K-2 classification. USCIS and the consular officer both verify eligibility before issuing the visa.
  • The child must be the biological child or legally adopted child of the K-1 visa beneficiary — stepchildren do not qualify unless a legal adoption has been completed
  • The child must be under 21 years of age at the time the K-2 visa is issued by the consulate — age is determined at the date of visa issuance, not the date the petition is filed
  • The child must be unmarried at the time of visa issuance and remain unmarried throughout the K-2 process — marriage at any point before adjustment of status disqualifies the child
  • The child must be admissible to the United States and pass all required background checks, medical examinations, and security screenings
  • The child must not have any independent immigration bars such as prior deportation orders, fraud findings, or criminal inadmissibility grounds
  • Children of all ages from infants to 20 years old qualify, though each child over 14 must attend an individual consular interview

Filing Process: Adding Children to the K-1 Petition

The U.S. citizen petitioner includes K-2 children on the I-129F Petition for Alien Fiancé filed with USCIS. Each child must be specifically listed on the petition with their full legal name, date of birth, and country of birth. Failing to include a child on the original petition requires filing a separate I-129F or amending the pending petition, which adds significant processing time.
  • List every eligible child on Part 3 of Form I-129F when filing the initial petition with USCIS — include full legal name, date of birth, city and country of birth for each child
  • Provide a certified copy of each child's birth certificate showing the K-1 beneficiary as the parent
  • If the child was adopted, provide certified adoption documents establishing the legal parent-child relationship
  • Submit passport-style photographs for each K-2 child along with the petition
  • After USCIS approves the I-129F, the case transfers to the National Visa Center (NVC) and then to the appropriate U.S. consulate abroad
  • Each K-2 child completes their own DS-160 visa application and schedules a separate consular interview appointment
  • Children under 14 typically do not need to appear for an in-person interview but must still complete the DS-160 and medical examination
  • Pay the K visa application fee for each K-2 child at the consulate — this is separate from the I-129F filing fee

K-2 Visa Processing Timeline

The K-2 visa processing timeline follows the parent's K-1 petition. Children cannot receive K-2 visas before the parent's K-1 petition is approved. The following timeline reflects current processing times for K-1/K-2 cases in 2026.

Aging Out: What Happens When a Child Turns 21

Aging out is one of the most serious risks in the K-2 visa process. A child who turns 21 before the K-2 visa is issued loses eligibility for K-2 classification permanently. Unlike some family-based visa categories, the Child Status Protection Act (CSPA) does not apply to K-2 visas. This means there is no age freeze or subtraction of processing time — the child's actual biological age on the date the consulate issues the visa determines eligibility. Families with children approaching 21 must plan strategically to avoid this outcome.
  • The child's age is measured on the date the K-2 visa is issued at the consulate — not the date the I-129F is filed or approved
  • The Child Status Protection Act (CSPA) does not protect K-2 visa applicants from aging out — there is no processing time subtraction
  • Once a child turns 21, they are permanently ineligible for K-2 classification regardless of when the petition was filed
  • For children close to turning 21, the U.S. citizen petitioner should file the I-129F as early as possible and request expedited processing if available
  • If a child ages out of K-2 eligibility, the U.S. citizen stepparent can file a separate family-based I-130 petition after the marriage — but this requires the child to wait in the appropriate preference category
  • Children who age out cannot use the K-2 visa to enter the United States even if the I-129F was approved before their 21st birthday
  • Strategic planning with an immigration attorney is essential for families with children between 18 and 20 to minimize the risk of aging out

Adjustment of Status After Arrival

K-2 children who enter the United States must adjust their status to lawful permanent resident (green card holder) after the K-1 parent marries the U.S. citizen petitioner. The marriage must occur within 90 days of the K-1 parent's entry into the United States, and K-2 children must file their own adjustment of status applications. K-2 children adjust status based on the marriage of their parent to the U.S. citizen — the U.S. citizen becomes their stepparent, and the adjustment is filed under the immediate relative category.
  • The K-1 parent must marry the U.S. citizen petitioner within 90 days of entering the United States — this deadline applies to the entire family
  • Each K-2 child files a separate Form I-485 Application to Register Permanent Residence or Adjust Status
  • The I-485 filing fee applies to each K-2 child — children under 14 filing with a parent receive a reduced fee
  • K-2 children must submit a new medical examination (Form I-693) with their I-485 application
  • Biometrics (fingerprints and photographs) are required for K-2 children age 14 and older
  • K-2 children receive conditional permanent residence (2-year green card) because the marriage creating the stepparent relationship is less than 2 years old at the time of approval
  • The family must file Form I-751 Petition to Remove Conditions on Residence before the 2-year conditional period expires
  • K-2 children who turn 21 before their I-485 is adjudicated may still adjust status if the I-485 was filed while they were under 21 and unmarried

FAQFrequently Asked Questions

Q:Can my fiancé's children come to the U.S. on the K-1 visa?

A: No. Children of K-1 fiancé visa holders enter the United States on the K-2 derivative visa, not the K-1 visa itself. The K-1 visa is exclusively for the fiancé of the U.S. citizen petitioner. Each eligible child (unmarried and under 21) must be listed on the I-129F petition and receives their own K-2 visa after completing a separate consular interview and medical examination.

Q:What happens if a K-2 child turns 21 during processing?

A: The child permanently loses K-2 eligibility. The Child Status Protection Act does not apply to K-2 visas, so there is no age freeze or processing time subtraction. The child's age on the date the consulate issues the visa determines eligibility. If the child turns 21 before visa issuance, the U.S. citizen stepparent must file a separate I-130 petition after the marriage, and the child will wait in a family preference category.

Q:Do K-2 children need to file their own adjustment of status?

A: Yes. Each K-2 child must file a separate Form I-485 to adjust from K-2 nonimmigrant status to lawful permanent resident. The adjustment is based on the stepparent relationship created when the K-1 parent marries the U.S. citizen petitioner. Each child needs their own I-485 application, medical examination, biometrics appointment (if 14 or older), and supporting documents.

Q:How long does the K-2 visa process take from start to finish?

A: The complete K-2 visa timeline from I-129F filing to U.S. entry typically takes 10 to 18 months. USCIS processing of the I-129F petition takes 6 to 10 months, followed by 4 to 6 weeks of NVC processing, consular interview scheduling, and visa issuance. After entry, the family has 90 days to complete the marriage, and adjustment of status processing adds another 8 to 14 months.

Q:Can a K-2 child work or attend school in the United States?

A: K-2 children can attend school immediately upon entering the United States — no work authorization is needed for school enrollment. For employment, K-2 children can apply for an Employment Authorization Document (EAD) by filing Form I-765 after entering the U.S. They can also file for an EAD concurrently with their I-485 adjustment of status application. Work authorization is typically granted within 3 to 5 months of filing.
