Is there a 7 day window after the due date or has that gone?

Thanks

I have "transferred" from a retirement to marriage visa and am married to a Thai citizen. Have been living here for 12 years and plan to continue to do so. I never really paid much attention to all these categories till I was obliged to change visas for financial reasons. Your point 4) is very interesting. What does the A in OA stand for? (How I "transferred" is a long story which I posted about earlier, not relevant for this thread in case anyone wants to enquire).

And that could happen any year, not just at the initial application?

Very clear explanation. Thanks.

I'm not surprised :-)

What I was concerned about was a) whether I should get a re-entry permit before leaving Thailand in case my plan fell down, or would that just confuse immigration at Suvarnabhumi if I returned with a new visa? b) can a single entry non-immigrant visa be converted to a marriage visa and I guess the answer is yes ("Phew").

Thanks. The Glasgow consulate accepts personal visits with a turnaround of 2 - 3 days

OK - thanks for all the replies. Here's my plan. [My retirement extension expires 17 Jul] Comments welcome. a) IO says she can grant me a 60 day extension if I can supply her with more documentation (I will tomorrow) b) this would get over the fact I need to be in the UK 3 Aug to 25 Aug c) while in the UK (far from London) I visit the local consulate and apply for a single entry non-immigrant visa d) I enter Thailand using the new visa which is valid for 90 days e) 30 days before it expires I apply for conversion to marriage visa. Would this work?

This is part of my plan - see later post.

Alexey Shipulin Good to know the income option is not universal.Probably best to at least start with the 400K.
