Your work information is not stored in SEVIS system. Since the officers at the POE can only spend 90 seconds with an individual they do not have time to look into other records nor do they have access to it. The only thing they need is you current I-20 endorsed for travel, valid passport/visa and proof that you have been maintaining your status. It is advisable to take your current transcript and a letter from your school but rarely would they ask to see those. Only if they have any doubts based on what you say or on the documents you provide then you will be directed to the secondary inspection for further questions. But work along does not pull the triggers for further questioning.

Good Luck!
