Why do you have quit job cos u wanna change reason for stay, I didn’t quit my job when I did that few years ago tho local immigration in my province told me same thing but I just waited till my visa ran out n switch and I had all requirement ready, a month to my visa running out I asked my employer to cancel for me and I switched and for your working permit u can have multiple working permit on marriage visa and I have evidence of that
Only con is if you purchased it in state it will be difficult to sell in Thai unless a foreigner buys it from you, they always prefer keyboard with Thai inscription, couldn’t sell mine after taking it to multiple shops, aside that nothing else.
