US Immigration from Colombia

I have been on the AOS process for more than a year and I am travelling for a week to Colombia to see my mom by the end of September. My passport expires in November and I am not sure if the US government will allow me back (even though I have permission to travel and am in the middle of AOS), because my passport expires in less than 6 months.

Has anyone changed their last name for the one of your future husband/wife before the actual wedding?

i've thought about doing it so I can change all my documentation in my home country, but my main questions are:

Would it affect in some way the visa process?

if not, would I need to do it before sending the I-129 package?

Thanks in advanced.

We showed up a little early and waited in the plaza. About 15 minutes before the ceremony, they asked the candidates to line up (probably around 20). I went in as an interpreter and had no problem as we did answer yes to one of the questions. (travel since the interview). An officer quickly viewed the questionnaire and marked the days of travel and sent us to another short line to a window where an Immigration Officer asked for the travel dates again, proof of vaccine (we had returned from our trip 10 days but that may not have been enough) and then for the new and old green cards. The Officer sent my wife to a seat with the packet containing the oath, flag, and said I could move an unoccupied chair next to hers. The ceremony was moving and I noticed that my sister and brother-in-law were outside waving and since it was dark due to an impending storm, they could watch the proceedings! The funny thing is that my brother-in-law is a federal judge and swears immigrants in from time to time! The Officer mentioned SSA, passport and voting information. After the ceremony they call the new citizens up and give them their certificates which you are supposed to check for errors.

I am glad we brought the vaccine cards as the USCIS Notice of Oath Ceremony does not mention them. However, the USCIS website says you can't enter if "Returned from domestic air, international air, or cruise ship travel in the past 10 days (unless you are fully vaccinated)."

I mailed my I-130 form in. Does UCIS notify you when it is received?

Hi Guys:
