US Immigration from Mexico

Hi everyone. I hope someone can help me out with this. I just called NVC today and they told me they received my case but no number assigned yet. They also told me that I cannot schedule anything until it is sent to the consulate in CDJ and I get a letter. With this being said, I know many people schedule an interview once they have the NVC case number. Is this recommended for Mexico? How long does it usually take to get the famous Packet 3/4. I know it is hard to schedule an appointment at CDJ so I am just trying to stay ahead of the game. I have also read that worst case scenario you can get a copy of that letter before the interview. My fiance lives in Mexico City so he would have to do medical and fingerprints in Mexico City but then he will also need this letter for those appointments? I would appreciate any advice. Thanks!

It is a K-1 visa, by the way.

Me and hubby married April 2018. He got his conditional GC sept 2018. We're filling ROC on july/july this year.

I filed i130 for his kids in mexico, I'm waiting for their interview in Mexico. They should be here this year or next year.

My question is, if my husband's ROC is still pending when the kids enter the US AFTER april 2020(our 2 year anniversary) are the kids still conditional residents or they get the 10 year GC?

Quick questions:

I'm the sole income for our household. She currently resides in Mexico and is a full-time university student with no income of her own. She does not have an ITIN or SSN as we are currently in the process of waiting on our I-130 Petition.

I've read that it's best to file as MFJ for our situation, however, she needs to get an ITIN to get things started. I've read on the IRS site that you can go through an Accepted Agent Program and they can help you both file and receive an ITIN. We have done some research and found that there is a Deloitte office in Juarez close to us but I was curious as to how they will help us? Are they basically there to just verify documents without needing to send them in through mail? I'm assuming this saves some time, because my other question is would it be the same if we just mailed our the correct certifying documents to prove her Foreign Status & Identity along with my tax return to the office specified in the instructions for the W7 application?

Thank you for all the help!

Someone knows how long it takes to get accepted in the California office of the I-130, I sent the package on October 16, 2018, I got an answer that the package had arrived on July 20, 2019, they still do not accept me and never huh I went to the USA and I have an American daughter and they still don't accept me. Do you think I receive my green card this year?

my case starts with ioe

I wanted to hear people's experience. My mom has her interview next month in Juarez ( FEB 2020 )

I am the petitioner we submitted the waiver got approved.

I just want to see which questions would she be asked?

She came since 1985 and never left

We have everything ready for our trip.
