International students attending Thiel College are in the U.S. on F‑1 immigration status. An F‑1 student may remain in the U.S. for a period of post‑graduation practical training that is directly related to his or her field of study after receiving authorization from U.S. Citizenship and Immigration Services (USCIS). The college refers to this as Optional Practical Training (OPT). The International Student Affairs office assists students with the OPT application process and ensures students maintain valid immigration status throughout their program and after graduation.
