Taking over for deceased petitioner ---- What forms, requirements must be met

[nemozed 1]

My wife's cousin's late father filed an I-130 form to bring her sister over from the Philippines. The petition was approved. After a prolonged delay the father died. Now my wife's cousin is trying to resume the procedure to bring her sister over. The USCIS sent a letter stating that the petition can be resumed provided that that the beneficiary write a letter explicating the humanitarian reasons for reviving her petition and listing the names, relations and locations of all of her relatives.

My wife's cousin will have to fill out and fully document I-864 form proving her ability to financially support her sister.

But she is unsure about what else she has to do. So I am here trying to gather information for her.

When I did the finance Visa for my wife we both had to fill out G-325 forms, multiple copies for each. Is this a requirement also for a legal American resident trying to bring a sibling over?

My fiance had to get a NBiI Clearance, an official NSO birth certificate and a Philippine passport. I assume that these things will also be necessary for a relative that someone here is attempting to sponsor.

My wife had to undergo a medical exam and an interview at the U.S. embassy in Manila. I assume that this will be the case for the sister as well. Am I wrong?

Please correct any inaccurate assumptions that I may have about this process. I would appreciate any information that anyone would care to provide.

I went through the B-1 process with my wife. This process may be similar in some ways but I suspect it may also be different in others.
