What visa should I apply for my upcoming trip to Thailand for two months after New Year, considering my history as a long-term resident and my marriage to a Thai?

Hi Guys.

Information needed.

I hope to be traveling to Thailand in early January just after New Year.

I have been traveling, living, and working in Thailand since 1995. I have been married to a Thai for 4 years and usually get myself a 90-day marriage visa and extend when needed.

This trip I might only be visiting for 2 months so not sure which visa to go for.

My question is, can you guys set me up a list of everything needed for my next visit. ( Been in Uk since Oct 20. )

I understand that things might change before January.

Thanks all.
