Again about the TM30.
I understand even if staying at a friends house, a TM30 has to be done with immigration. So far, so good.
In the past I have never done a TM30 while on visa exempt staying at my girlfriends house (out of ignorance, I simply didn't know). And as a matter of fact I never ran into problems driving around in Thailand. And I travel a lot when I am in Thailand (and I understand when I stay at a hotel, the hotel will do the TM30).
It was written here that if you have not filed a TM30 and then have anything to do with the immigration office (e.g. an extension), then there will be problems (a fine, or whatever).
The question is, will the fact that I (or my girlfriend as the house owner) did not file a TM30 in the past haunt me later should I apply for a retirement or marriage visa in the future? Will or can immigration check my past compliance (or lack thereof) with regard to the TM30? Will I then run into problems applying for a retirement or marriage visa?
Thank you.
