I always protested entries without revised 7501. However, CBP at port of Savannah GA require revised entry summary to be included with the entry packet. My argument for not including revised 7501 was that since protests are codified in 19 CFR 174.13 where no provision for revised entry summary is mentioned, no revision is required. 1703 is different.
Recently I got a call from Newark entry specialist requesting the same thing. They, however, have teams that require and that don’t.
All other ports don’t require revisions to the best of my knowledge.
