A visa is official documentation from the host country allowing you to enter and stay in that country for a specific purpose and specific period of time. Some countries require study abroad students to obtain a visa prior to travel. There may be different processes and requirements depending on your citizenship and the length of stay. Check with the embassy of your host country for more information.
For Consulates that ask TCU to apply for student visas as a group, we will apply on your behalf. But you must provide all the necessary paperwork, exactly as requested.
A visa is stamped in your current passport; therefore, your passport will be submitted with your visa application. Do not make plans to travel internationally for the duration of this process.
