Compared to most countries Thailand has a very relaxed visa regulation. There are few if any countries at all, where you can stay as long as you like without having any specific purpose for staying there.
You won't have any issues extending 30 days at your local immigration, but if the IO told you that no one is getting denied entry at the borders she is greatly mistaken. It is a daily occurrence, and sooner or later you will be denied entry. Trying to live here on TVs and exemptions is not a possibility.
I thought that my reply would uncover that question, but with limited English skills, I might have failed of making myself understandable. 🙂
It makes no difference if you have a party or no party, or if your party was 8 or 80 years ago. A Thai ceremony is not legally binding, and therefore has no saying in a real marriage.
If you attend classes or not is none of my business or concern. 🙂
I have previously been on ED visa, and took a few short holidays out of the country. On 2 out of 3 trips I was questioned upon return by immigration and was only curious if that could happen if you travel around Thailand.
Does anyone know if filing with immigration could cause any issues? I think in the eyes if the law, people on ED are supposed to follow classes, and not travelling around the country.
