Maybe it's because I have never financed a car, but I sure can't recall ever providing a social security number on any car transaction.

Why would they ask for your social security number to buy a car, I would tell them to pound sand. 
 
I got a 2018 Honda last year off the lot, just wrote a check for it and took about 20 minutes signing papers and declining all the add on like: New car warranty, Paint protection, etc.

If one of you is a US Citizen, consider marrying online via Utah online weddings.  From that point on you are already legally married in the eyes of the US, and you can apply for spousal visa CR-1.

In my experience, EVA Airlines is an excellent airline.  The only horrible thing I can think of is the Hello Kitty themed gate area in Taiwan.

Don't worry yourself to much about the CFO. Some officers can be rude and try to use scare tactics. Just be confident in your answers and be strong. 
My wife went thru CFO a few of years ago, when you actually met face to face. They told crazy stories about foreign husbands (American) only wanting house keepers and sex slaves. Trying to find a reason for you to second guess yourself about the whole process. 
Also don't worry about age gap. My wife and I have about a 25 year difference. 

First off, that's not really a huge age gap. Its actually pretty common. My wife and I are25 years. Like Top Secret said, be confident not timid and you will be fine. Second, don't worry so much. All my years on this forum I have seen some be given a hard time, but I don't recall anyone that did not receive their sticker in the end.

I know this thread is a bit old but I wanted to post some updated information. I sent a message on their website contact form asking for clarification on IF both parties (husband and wife) need a notarized signature if we live in separate countries (me USA, her Philippines). This is the email response I received:
 

So for couples that marry and are currently living in separate countries only 1 notarized signatory is required. Hopefully this will save others a bit of time.

At this point, no matter what happens, just make sure that she arrives in USA after 6/3.

Now that the fees to adjust your status after a US marriage have doubled,   spouse visa makes mush more sense as both K1 and CR1 take about the same time.
 
If u will not return to Nigeria to live,  send for the criminal report documents that will be needed for your Finland interview.
If u do return to Nigeria for an interview ,  make sure u get a Finish criminal report before u leave.
 
what is important now is that you have over a year to show more trips to be together and you can prove it with  copies of boarding passes,  hotel receipts ,  etc 
time spent together will be very important to your case.
 
It would be best if the USC joined the site for information as she is the one who now is responsible for the process

Actually the opposite--the CR1/IR1 is far simpler, cheaper, and generally faster than the K-1.  The K-1 will cost you many hundreds of dollars more (possibly thousands with pending fee increases), not to mention additional paperwork filings, etc.  and your marriage will be in a sort of grey zone until the US gov't is confident it's going to last (you have to go to interviews proving it's a legit marriage once back in the USA, file a bunch more documents, pay hundreds in fees for each one, etc.) versus the CR1/IR1 which is simpler, faster, easier, requires less documentation, and upon entry to the USA your foreign bride has all the benefits an American spouse has (except voting).  Plus it's the general consensus of the forum that CR1 is superior, as long as you are ready to commit to marriage.
 
I was in the same boat as you this time last year (even asked my Filipina gf who I got to know very well during covid-19 lockdowns if she would do the online marriage before our first physical meeting but she was reluctant).  We treated the online Utah ceremony as a civil union, applied for the visa, and then later travelled there for the romantic proposal and planning of a ceremony for her friends and family to enjoy.   Then an additional trip back for the ceremony.  If you do it this way, then the 2 year waiting period is slightly more manageable because you have mini-goalposts spread out during the process instead of just years helplessly waiting for a bureaucrat to process your file.
 
Note that you have to be together DURING OR AFTER the Utah wedding BEFORE you can file for a US spousal visa, so if you don't complete the Utah wedding while you are both together on this trip, you will need to visit her again before you can start the long US visa application process (you will need passport stamps to show physical presence together).

By the way if you do the Utah wedding option, I HIGHLY recommend Rev Chris at Universal Heart Ministry.  I wasn't expecting an emotional event, just checking boxes for a bureaucratic form, but he made the event extra special and followed up with a very nice card for something absurd like $50.  Just remember at some point you have to register your marriage with Philippine authorities (it's been a year and we still haven't started) and otherwise just follow the guides here.
 
 
Fully remote is fine, you just have to be physically together as man and wife once, so visit either DURING or AFTER the Utah ceremony.
 
Finally, ignore the occasional pessimism on the forum (people accusing you of fraud, people defending the US government's ridiculous immigration system, etc.); it's actually a superb resource.  Best of luck to you!
