Thanks Nick but my marriage certificate is by the Singapore (SG) government. It is a legal document. Not need further verification in SG.
We can’t do trailing spouse visa based on retirement anymore unless it’s for working or studying only. I checked with the Thai embassy in SG. I think the Thai embassy in many countries have stopped it.
A consultant told me that I need to legalise my Singapore marriage certificate in Thailand which I find odd. First time I heard it. I’m checking if it’s true.
