What are the K4 Visa requirements?
If your children want to follow you in the U.S., they must meet the following requirements:
- They must be unmarried;
- They must be under the age of 21;
- In the case of stepchildren, the relation with you must be created before they reach the ages of 18.
It is worth noting that the K4 visa status applies only to children of married couples. If you and your partner are not married, you must follow the K2 visa process for dependents of foreign fiancé(e)s.
