USCIS has not provided comprehensive instructions on completing Form AR-11. Some of the questions are confusing and have not been clarified by USCIS. As far as the ISO can tell, the form will be most useful to USCIS if you provide information in the following way:
"I am in the United States as:"
If you are a J-1 Professor, Researcher, or Short-term Scholar, check "visitor."
If you are a J-1, F-1, or M-1 student, check "student."
If you are an H-1B temporary worker, J-2 spouse or dependent, B-1 visitor for business, adjustment applicant, O-1 individual of extraordinary ability, or in another nonimmigrant status, check "other" and write in your visa type.
If you do not have an "A" number from an alien card (permanent resident card), you may cross out the A and write "I-94 number" and then fill in the I-94 number from the Form I-94 arrival/departure record in your current passport.
"Port of entry into the U.S." should be your most recent port of entry as stamped in red on your Form I-94 or in your passport.
"Date of entry into the U.S." should be the date of your most recent entry as stamped in red on your Form I-94 or in your passport.
"My stay expires on" should be completed with the end date listed on your Form I-94 and immigration documents. If you are in J-1 status, your expiration date will be D/S plus the ending date on your most recent Form DS-2019. If you are in F-1 status, your expiration date will be D/S plus the end date of your Form I-20 or Practical Training period. If you are in H-1B or O-1 status, your expiration date is the end date listed on your Form I-797 approval notice.
