US Immigration from Mexico

I'll be pursuing a CR-1 spousal visa for my wife and CR-2 for her daughter, which was under 18 at the time of our marriage. I'm looking at submitting the I-130 form for both next week. Would it be beneficial to go ahead and complete the I-485 at the same time, and file them both together? I'm considering the increase in fees that go into effect April 1, 2024. Thoughts?

This is still a ways off for us, but as with everything USCIS-related, we want to be as prepared as possible.

My husband entered the U.S. on 9/23/2023, and my stepdaughters entered on 11/23/2023. Per the filing date calculator, we can file I-751 jointly starting on 6/25/2025.

My questions/clarifications:

1. Even though the 90-day window won't be open yet for my stepdaughters, they can be included on their dad's/my husband's I-751, correct? (pay 1 filing fee + 4 biometric fees)
2. At the time of filing in June 2025, their ages will be 20, 18, and 15. They are still considered "dependent children" as USCIS refers to in the instructions, correct? They received their green cards as a result of their dad's marriage to me (USC).
3. I'm confused by the new filing fees with the biometrics included for situations like this. Would we pay $750 for my husband (751 w/ biometrics included), plus $30 additional biometrics for each stepdaughter? ($840 total)

Appreciate your help. Wouldn't have gotten this far in the process without VJ's help!

I was wondering if anyone has an estimate of refund waiting time when you file your first mfj w7 return. Months a year? I ve read that some people wait a year before it s processed, trying to see if this is typical as we will need the money sooner than later.

Secondary question, I think somewhere I read it s better to file mfj at minimum the first year but I can t remember why.

thanks everyone!

Just wondering if anyone could share how long it took to get an interview date once they got their dq and file was sent to nvc?

thanks all

title basically says it. My beneficiary has a different address on the DS-160, and on my I-134. The reason is because she was living at a different address when we filled out each document. Is this going to cause an issue? What should I do if anything.
