, Usually, your employer gives you a termination letter. You bring it to the labour office that issued your work permit to cancel WP, then bring the WP cancellation receipt (and letter if you get it back) to the immigration office to cancel the extension. In many provinces, you can do it a few days or weeks in advance, but some provinces accept the WP cancellation only on the last day of your work. The order of applications might be different in some provinces.
You need to talk with your employer for a detailed procedure. Some employers accompany you for part or whole of applications. Some employers cancel your WP first, and then give you a cancellation receipt. A work permit can be cancelled by the employer, but an extension cannot be cancelled without you and your original passport.
Basically, that is correct. As a rule, you have to apply for a visa through the eVisa system through the embassy of the country you are physically staying in.
But it depends on the embassy and type of visa (requirements) if you really can apply for a visa there or not. Some embassy requires you to have legal residency in that country for selected visas. It hugely varies by the Thai embassy/consulate which types of visas require legal residency. You need to check them.
That "maximum two times by land for visa-exempt entry" rule has not been applied for current 60-day visa-exempt entries since last July. So there is no "use up" or "reset" now. Your next entry to Thailand, regardless of whether it is through a land border or by air, will be considered by the officer who handles your entry at passport control at the entry point. Be ready for the worst scenario if you have an extensive history travelling in Thailand on a tourist status.
, If you leave Thailand without a re-entry permit, your extension of stay is no longer valid and you cannot enter on it again, but it is not officially cancelled. You can enter again on visa-exempt for 60 days.
You have to be sure to cancel your extension if you want to travel through land borders. Some borders don't let you leave with an uncancelled extension stamp, even if it's expiring.
Q. Did it change or is it because I have entered the kingdom with a reentry visa (not multi entry)?
-> It IS because you entered on a re-entry permit.
You don't have a multiple entry visa any more. You have now 1-year extension based on marriage to a Thai and a valid re-entry permit.
A re-entry permit wouldn't give you any additional stay further than your current stamp. You will get the same date as your current extension every time you enter.
, No, as financial proof for an extension based on marriage to a Thai is not tricky like one based on retirement.
The basic concept is roughly the same as retirement. Anyway, not many immigration offices accept the monthly transfer method for a 1-year extension based on marriage to a Thai.
First of all, you have to check with your local immigration office whether they accept 65K monthly deposit method for an extension based on retirement.
If the embassy of your passport nation in Thailand issues an affidavit, you need only that for financial proof.
In case your embassy doesn't issue affidavits (US, UK, and AU are among them)
1. A 65K monthly international transfer method can be used only for a 1-year extension for the second year or later. You cannot use the monthly deposit method for the initial in-country Non-O visa based on retirement or the first yearly extension for retirement.
2. You need more than 12 months of international transfer, at least 65K per month, as of application day for a one-year extension based on retirement.
3. If you applied for a yearly extension using banked money of 800K baht, you have to keep 800K for three months after an extension is approved and no less than 400K baht for the rest of the year until you get approved for next year extension regardless you do monthly transfers of 65K.
If you mean switching 2 to 3, you must keep BOTH for a year when transitioning.
Attached is a rough image of how to switch the financial proof methods. It may or may not help..
It would affect when you apply for an extension next time if you don't officially cancel the current extension. The uncancelled extension will be an "open extension record" and you cannot apply for an extension, especially for a Non-Imm-based extension, if your history has an open one.
In other words, if you are no longer coming back to Thailand for good, or not more than the minimum stay as a tourist, you can just let it expire and leave. and you wouldn't have an issue with just a short holiday trip to Thailand in your future.
, for that, you have to submit an extension application which is to be rejected with the 1900 baht usual extension fee so that they can give you (up to) 7-days-to-leave-kingdom stamp. No extra days stamp for free.
