What is an important requirement for a spouse of a B visa holder?

The requirement that a spouse of a B visa holder must obtain their own visa is rooted in the U.S. immigration system, which distinguishes between different visa categories and their associated rights. When a non-citizen is in the U.S. on a B visa, which is typically for tourism or business, that visa does not automatically confer any immigration benefits to their spouse. Therefore, the spouse must independently apply for and obtain a visa if they wish to accompany or join the B visa holder in the United States.

This system is in place to manage immigration accurately and ensure that individuals entering the U.S. have the appropriate legal status based on their specific circumstances and visa type. Spouses cannot simply accompany a B visa holder without following this requirement, reflecting the need for compliance with immigration laws.
