Temporary visitors for business/ Temporary visitors for pleasure

The "visitor" visa is a nonimmigrant visa for persons desiring to enter the United States temporarily for business (B-1) and for pleasure or medical treatment (B-2). Depending on the purpose of visit and need for length of stay, visitors are permitted to stay up to 6 months. It is important to note that visitors are not permitted to accept any form of employment during their stay in the United States. Therefore, one should apply for change of nonimmigrant status if the purpose of visit changes during his or her stay in the United States. Also, special circumstances and/or important considerations may warrant an extension of stay.

Spouses of E-1 or E-2 visa holders are eligible to apply for employment authorization once admitted into the United States.
