OK< thanks, everyone.

Be careful crossing between the Malaysian station and the Thai station (of the same name), in order to allow enough time to catch your onward train. Border staff I encountered (Thai side) were difficult to deal with and asked for financial evidence and a couple of other things I didn't have (this was three or four years ago). When he realised I had a train to catch he stamped my passport and let me pass. Good luck!

Yesterday, before posting here, I went to immigration at CM airport, queued up outside to see a volunteer adviser. Eventually, I was told I would need to speak to an officer about this issue. (Confusion seems to reign supreme!) The queue inside immigration was such that I couldn't face it. Could be I have to try again and hope to get a straight answer on this point from inside the building. When I was in the process of renewing/extending my visa last year, I asked the very same question and understood from the answer I was given that funds had/have to remain in the account for 'three months' (rather than 90 days) after the extension. I just want to DOUBLE check that point.

Thanks very much for your replies, gents. However, I fear I'm none the wiser : /

I was just told by the TM30 staff in CM immigration that, with my re entry stamp, no TM30 update is needed. Hurrah, some common sense in the proceedings!

@James *******

Thanks for the reminder. I checked my account and fortunately, fortuitously and thankfully I kept my balance above 400,000 throughout.

Many thanks. 2) sorry TM8 isn't a re entry permit. It's notifying immigration of my having re entered the kingdom, as I understand it. Don't think I've filled one in before.

Thanks for the quick and clear replies : )

Tod, I think I'm beginning to understand. At least part of my confusion is caused by the fact that I failed to do the re-entry permit thing last year. Hence, my non-immigrant O ('admitted until 25 Jan 2022') had USED stamped on it and I had to start again (or did I?) with the application paper work. The latest 'receipt of notification' form has THIS IS NOT AN EXTENSION OF STAY stamped onto it.

Thanks. In terms of the visa itself, is it renewed at the end of 12 months or does it have to be applied for again, from scratch?
