Visiting From Abroad
Important information from the U.S. Citizenship and Immigration Services (USCIS):
Medical care in the United States can be very expensive. All visitors are advised to carry valid health insurance for the duration of their stay.
Driving in the United States
Visitors who wish to rent cars must have a major credit card and a valid driver's license from their home country. In some cases, an international driver's license may be required. Contact the car rental company directly for specific information.
Required Change of Address Notice
Visitors staying in the United States longer than six months must notify the U.S. government of any change in their residential address within ten days or face serious consequences. Address notification should be made directly to the U.S. Citizenship and Immigration Services (USCIS) using their required form.
Registration in the US
Federal law requires that all non-U.S. citizens carry evidence of their lawful status with them at all times. This is especially important for all travel, international or domestic. It is advisable to keep copies of all pages of the passport, visa, I-94 Arrival-Departure card, and supporting documents such as DS-2019 forms, in a safe place in case of loss of the original documents.
