US Immigration from Colombia

I recently applied for my passport and my 11 year old daughter s, as well. Her biological father lives overseas and signed the DS 3053 form of passport consent. The form was virtually witnessed by a notary in the states. I recently received a letter from the passport office saying I needed to provide the consent again but signed physically in front of a notary and I needed to provide proof of custody, and additional documents proving that she has lived with me since she moved to the States. I was never married to her biological father and we have joint custody but she lives with me. We never had any sort of court ordered document that states the agreed living situation. I do have a swore statement that her father and myself did that allows my daughter to leave Colombia with either one of the parents. My questions are:

*if her father signs and gets the document notarized in the US embassy in Colombia will that suffice or does he also have to get a sworn statement that says he allows my daughter to physically live with me in the states. ( we have lived in the US for 4 years already)

*Also, how would the process be to get an appointment in the Embassy when he is not a US citizen?

*If her passport application isn t approved would we get her Green card back?

Fianc e is off tot he airport to fly to Bogot . Visa interview for K1 (and K2 for son) in Monday.

And, of course, just now I realized I completed the I-864 Affidavit of Support that typically is filed with immigrant visas and not the I-134 that is typically filed with non-immigrant visas like the K1. Damn.

In addition to the I-864 she also has:

Bank statement from 5+ years ago showing both our names.

Two credit cards on our joint accounts.

My IRS Transcripts for last 3 years.

My most recent year's W2.

Copies of all my paychecks for past 6 months.

Is this a problem? Anyone submit the I-864 on a K1 visa in Bogot ?

Im from chicago where can I find interview followups from people who went to chicago for interview i485?

Trying to figure out my tax situation and want to verify what a tax accountant told me. My wife moved her dec 26 and we got married on dec 27. Tha accountant told me she doesnt need to file this year since all of her income was when she was out of the country and i can file married filing separately. Is this because of the substantial presence test?

Would we have the option to file jointly if we wanted as it seems like we might get a bigger return since she didnt make much in her home country?

Can we file while for mother while she's in US on a tourist visa? Any issues from overstaying visa while waiting ?
