US Citizens and foreign nationals coming to the US for a temporary stay may legally bring their nanny or other domestic help with them by securing a B1 visa. These employers are typically senior executives for large corporations and certain US government employees routinely posted abroad. The US State Department, which oversees the issuance of the B1 visas, imposes certain requirements on the employer to ensure that the foreign domestic worker is treated in accordance with US labor laws and is not exploited.
