Have you considered any other visa options, than the spouse visa?
“I didn’t know that it could be so hard if you were married to a citizen.”
My GF, fiancé, wife was denied 3 tourist visas in 2008/9/10 and a fiancé’ visa in 2011. So I said F@@k it, quit work and moved to Thailand. Note all this cost thousands of dollars. We had a daughter in 2013 and decided to try for again for a tourist visa in 2017, and finally got a 10 year multi-entry tourist visa (which is all we wanted in 2008).
Came to the US and decided out daughter needed to educated in the USA, put her in K in 2018 leaving every 6 months to keep the wife’s visa valid.
Started in Dec 2018 for a sponsor visa, USCIS said 5 months, after 13 months still no joy. But it is possibly soon, which means less than 6 months in USCIS counting.
