US K4 Visa For Child

How We Work?


K4 Visa is a Non-Immigrant Visa intended for a child of a spouse that is applying for a K3 Visa and desires to bring his/her child to the US.

  • The K4 Visa application can be made at the same time as the filing of the K3 Spouse Visa application in Thailand.
  • The K4 Visa also allows a child of K-3 spouse visa holder to enter the U.S. and await the availability of an immigrant visa.


  • The applicant must be the child of a qualified K-3 visa applicant.
  • The step-parent/stepchild relationship must be created before the child has reached the age of 18.
  • The child must be under 21 years old at the time the visa will be issued at the US embassy in Thailand.
  • The applicant must be unmarried.


  • The child does not need a separate I-129F application for the US K4 Visa.
  • The US K4 Visa for the child will be approved at the same time as the spouse K3 Visa at the US Embassy in Bangkok.
  • The child will be allowed to live in the US while waiting for the immigrant visa processing.
  • The US K4 Visa allows travel outside of the U.S. on short trips and return.
  • With a US K4 Visa, the child is allowed to study and/or apply for Employment Authorization I-765
