How long can I stay in the U.S. with a B-1/B-2 Visa?
The US B-1/B-2 Visa allows foreign visitors to stay for a maximum of 180 days.
If 180 days is not enough for you, make sure you apply for the Visa extension 42 days before your I-94 Card expires.
Also, keep in mind that you can’t apply for the extensions in the first three months of your stay in the United States.
