Question to you all:
I am in the U.S. on a B-1 visa, and upon entry didn't realize that I was admitted for only 30 days. My flight out happens to leave exactly 1 day after the I-94 expires (and I am unable to change my flight at this stage due to a business obligation I have that day).
File for extension (a $300 endeavor), go to Mexico or CDN for a day, "lose" the I-94? Any suggestions would be greatly appreciated!
