US Immigration from Philippines

Hope everyone is doing great!

I need your advise please. I am planning to apply my parents a tourist visa. My parents are married but my mom is using her maiden name on her passport. Can this be cause of denial?
thank you all in advance!

Why it's taking so long to receive a welcome letter! My K1 Visa petition was approved back in May 27, 2022.

So I have read through all of these different things you need to do like the 10 day waiting period, planting a tree, counseling, getting a document from the embassy stating I am not married and my fiance getting something similar.

My Fiance's sister knows someone that works at one of the city halls in Manila and is telling me that I just need to pick a date and time along with both of our info, pay a fee, and then show up with our ID's to be married by a judge there in Manila. No 10 day waiting period, no tree, no counseling, no other documents... Is this legit? Is there a difference in marrying someone in the city versus the province?

We were also looking at doing the Utah online marriage while I was there. Is is better to get married in the Philippines or do the Utah thing? If this marriage with the judge is legit would it just be better to do it there or should I plan on the Utah online marriage. I am headed there in September so I have time. Thanks in advance for any help.

Will this be an email or a physical letter? I received this today, for my son who is an IR2, under 21 years old. How long till we get the notice?
