Establish a file to keep copies of all your immigration documents
IPS also keeps copies of some documents for a limited time only so you must keep your documents until you permanently depart the US.

Items to carry and keep with you at all times:
You should carry some basic information and documents in your carry-on bag. It is also a good idea to carry some essential items with you (change of clothing, medications, toiletries, etc) just in case your luggage is misplaced.  Review Permitted and Prohibited Items listed at the Transportation Security Administration.

a. Passport (keep a photo copy in your carry-on luggage)

b. I-20 or DS-2019 (keep an additional photo copy in your carry-on luggage)

c. I-94 (receive on plane). For nonimmigrant visitors entering the United States with a visa, there is a requirement to fill a Form I-94 (white form).  This form has two specific perforated sections to it. The visitor or the carrier representative fills out Form I-94 upon arrival in the United States. The bottom section of Form I-94 is a departure coupon and must be returned to U.S. officials upon exiting the United States The departure portion of Form I-94 and passport is to be in the applicant’s possession at all times until the applicant departs the United States .
