You are strictly forbidden from interning, training, or working for anyone other than your host employer. If you need to change employers, InterExchange must approve all requests for a change of host before you can begin interning or training for a new employer. Please contact InterExchange to obtain the required application for changing hosts.
You are never permitted to intern, train, or work for more than one employer at a time. Doing so violates the terms of your visa and immigration law and places your second employer in violation of the law as well. If you cannot financially support yourself, it is better to go home early than to break the law and jeopardize your chances of obtaining a U.S. visa in the future.
