Does the co-sponsor file a seperate I-864? He's married. Does he file with his wife? (They file taxes jointly.) - yes he does. he will check the box on the I-864 "I am the only joint sponsor". his wife would fill out an I-864A. https://www.uscis.gov/i-864a.
Is it correct that we do not need to file a separate I-864 for my step-daughter? - All intending immigrants must file an I-864 with their AOS packet. However, it can be just a copy of the one you fill out for your husband. From the I-864 instructions:
"Who Needs to Submit Form I-864? In general, the following immigrants are required by law to submit Form I-864 completed by the petitioner to obtain an immigrant visa overseas or to adjust status to that of a lawful permanent resident in the United States:
Person admitted to the United States as a K-1 nonimmigrant fiancé(e) or K-2 nonimmigrant child of a fiancé(e) of a U.S. citizen and who seeks to adjust status on that basis"
What do I check off on my I-864 to indicate that there is a co-sponsor (to cover the fact that I won't meet the
% requirement.) - the only thing you check on your I-864 is the first option "I am the petitioner. I filed or an filing for the immigration of my relative"
include a cover letter with you I-864, you can state in there that you are using a joint sponsor.
The doc from the US embassy in France who did his medical exam gave him a hard time about vaccs that he already had (she marked that he didn't have them when he had proof that he did... it was one of the ones you get in 2 or 3 and he had the 3.) He literally got everything that was on the list but apparently they changed the requirement the day before his appointment.
In any case, I think that means we have to get him signed off by a civil surgeon? Where do we go for that? I did do a search and came up with a list of names locally... is it just a doctor with a specific certification from the government? - you can use this from the USCIS site to find a civil surgeon https://www.uscis.gov/tools/find-a-civil-surgeon. you may want to shop around. a lot of them will not just do the vaccine portion of the I-693.
My husband and step daughter won't be active on my insurance until October. I don't know if it's wise to wait so I guess we're paying oop for that. - this is not covered by medical insurance any way. you will have to pay out of pocket regardless.
Facts that may or may not be relevant:
The co-sponsor does not live with us. He is a family member.
Also, for the I-765, (auth to work) do we have to file for the I-864 first? - you file ALL forms together (I-485, I-864, I-765) in the same packet.
I highly suggest watching some YouTube videos from people on how they organized their packets. It helped us a lot when we were putting ours together.
I also highly suggest you read the instructions for the I-864. This is the thing that most people get RFEs for - https://www.uscis.gov/i-864 - https://www.uscis.gov/sites/default/files/document/forms/i-864instr.pdf
