New version of form I-20 must be used after July 1, 2016
If you’re in F-1 status at Columbia as a student or on OPT after July 1, 2016, make sure you have the correct version of the I-20 when you travel. DHS implemented a new format I-20 on June 29, 2015 which must be used as of July 1, 2016.
Check the bottom left-corner of your I-20. "ICE Form I-20 (3/31/2018)" should be printed there.
