Visa

For most countries outside the European Union you will need a visa, for which you should apply as soon as you receive confirmation of acceptance from your host university. 

The embassy or consulate general of your host country will provide information and forms. For addresses see here.

Visa for the United States

Current regulations require all individuals between 14 and 59 years of age applying for a U.S. visa to appear in person at the consulate visa offices in Berlin or Frankfurt. Please remember this requirement in planning studies in the United States.

For more detailed information see the U.S. embassy website.
