It is important to plan ahead when it comes to international travel. International students must carry certain documentation with them during their travels.
You must have a Continued Attendance I-20 (or a Transfer I-20 from TWU) signed by a DSO endorsing travel. The signature must not be older than 1 year. You may request a new I-20 if the signature is close to a year old. Students on OPT & STEM OPT Extension should obtain a travel signature from a DSO every 6 months for international travel.
