RM2002,
I was told that Boston INS office can take EAD applications between 7 - 9 AM. In my understanding, there is no number limit for EAD apps during this period. I went to Boston INS office last week for my EAD (new) to return with empty hand. I got my AP from Boston office during first week of Nov '02, which i didn't use during my re-entry to US in Dec '02. I re-entered US using my valid H1, though i had AP with me.
