It is your responsibility to determine if a visa or residence permit is required for your program. To do so, you should consult with your host institution and the consulate or embassy of your host country. U.S. citizens can also find additional visa and country information on the U.S. State Department website.
If your program requires a visa or residence permit, you are encouraged to apply as soon as you are accepted into the program by your host institution and have access to the required materials. Failure to obtain a visa, or the correct visa, may lead to denial of entry and would not result in any program refunds.
If a visa is required, be sure to research what materials are required as part of the application. Some countries may require a bank statement showing sufficient funds to participate in your program, acceptance letters from host institutions, proof of health insurance, etc. The most up-to-date information on what will be needed for your visa application can be found on the host country’s consulate or embassy website. You will also be able to determine from the website if you need to make an in-person appointment with the consulate or embassy. If you need assistance, there are fee-based companies (visa agencies) that can aid you in the visa process.

NOTE: Visa application rules change frequently and the university cannot control visa acceptance. You are responsible for applying for and providing the proper documentation to the consulate or embassy.
