Tourist visas can be used only for leisure purposes. Tourist visa holders are not allowed to work or conduct business in the U.S.
The immigration officer at the port of entry will decide how long you can remain in the country, but tourist visa holders can't stay longer than six months.
If you entered the U.S. through the visa waiver program, you can stay only 90 days. Thirty-five countries are eligible for the visa waiver program.
If you are considering traveling for any purpose other than tourism, you must change the status of your visa.
Overstaying on a tourist visa can lead to deportation, and you can be banned from re-entering the U.S. for several years. If you are caught working while on a tourist visa, you could face criminal prosecution.
