Form I-539 is the application a nonimmigrant status holder uses to extend or change that status. For the H4 spouse, who accompanies the primary holder of an H-1B visa, it is the instrument that keeps their lawful presence in the country.

In practice, the H4 spouse files Form I-539 to extend their authorized stay (following the primary holder’s status) or to adjust some aspect of their own nonimmigrant status. Dependent children in H4 status are often included in the same application, depending on the situation.

One important point: the ideal approach is to file Form I-539 before the current status expires, so as not to create a period of unlawful presence. Keeping documentation in order and monitoring the H-1B holder’s status helps avoid complications.

Because requirements and forms can change, it is worth confirming the latest version and instructions with USCIS or with a qualified professional before submitting the application.
