I am faced with some of the same concerns... In any case check out my post entitled, "I-601 and HIV/AIDS". I included some links as well.
Good Luck!

Im really confused!

I found out last night that my finacee signed a waiver form after her second interview. She didnt know what it was until last night when I showed her the form. I called the for an update on our case and the operator said there was talk of a waiver in the notes. She said yes a waiver was added to the medical when it was sent to the CDC. I thought I had to fill out the waiver? I never have received anything about us being in the waiver process. I was also told by the Embassy that our case was sent to the CDC for an advisory. Why would they send a I-601 with it? Would the counselor fill out the form for us and then submit it or does the CDC have to approve a waivers in medical case before we can be offered it?
Plz. correct me if this info is inaccurate. It is my understanding that after the medical waiver packet (which includes supporting documents) are submitted to the consular officer by the beneficiary, the HIV or TB attachment is then forwarded to the CDC and the information is recorded. Supposedly the CDC faxes the document back to the embassy, in which the embassy sends the entire packet to Nebraska(?) for adjudication.
My spouses interviewing officer stated that the process typically takes about 5 months.
