I beleive they mean submitted with AOS paperwork. The affidavit of support used over seas at the visa interview was an I-134, the one used at AOS is I-864. The I-864 is a legal contract that is binding.

A...In most cases, no. The results of your K1/K2 medical were in the "sealed envelope" that you brought with you from your home country. The I-485 instructions mention that no additional medical is required if filing for AOS within a year of the medical required to obtain the K1/K2. You should simply send in a copy of the I693A (sheet that lists your vaccinations) that your doctor should have provided overseas when you had your medical. And...according to a newsgroup posting...."Went up to the local USCIS (INS) office in Omaha today and they told me that the letter saying "Adjustment of Status / I130 Interview" is just a form letter they send out whether you've applied under a I485 OR a I130.... They also told me that, despite what the letter says, I do NOT need to get another medical done even though its been more than 12 months since my K1 medical at the London Embassy."
