The law needs to be approved by the senate and endorsed by the king after that I'm sure the immigration rules on marriage will change to follow the new laws but I'm not sure about the timescale 👍🤔
I live 20km from the border at Aranyaphrathet but I always go to Bangkok and fly to Cambodia and back rather than have the hassle and uncertainty of the border immigration officers @ Poipet
I did my new passport visa transfers a few weeks ago and immigration required proof of payment either a receipt from HMPO or credit card/bank statement showing payment.
Apparently immigration has seen an increase in fake passports and that is the reasoning given... Dont shoot the messenger !
