Can I perform volunteer work while visiting the United States on a B-2 tourist visa?

Generally, performing any activity that constitutes 'productive work'—even if it is unpaid—is strictly prohibited while on a B-2 tourist visa. The B-2 visa is intended strictly for tourism, visiting friends or family, medical treatment, or short social events. U.S. immigration authorities view any labor that would normally be performed by a paid employee as unauthorized work.

However, there is a narrow exception for 'genuine' volunteer activities that do not involve traditional employment or professional services. For example, helping out at a local church or participating in a short-term, non-profit community service project that is purely altruistic and does not displace a U.S. worker is typically acceptable. You must not receive any form of compensation, including non-monetary benefits like housing or food, in exchange for your services. If you are found to be engaging in activities that look like employment, you risk having your visa revoked, being denied entry at the border, or being deported for violating your status. If you are unsure whether your planned volunteer activity qualifies, it is best to consult with an immigration attorney, as the distinction between 'volunteering' and 'unauthorized work' can be subjective at the discretion of the Customs and Border Protection (CBP) officer.
