, the penalty is only a fine, it's not an overstay fine, just the same rate as an overstay fine. 500 baht per day, maximum 20K baht.

@Mikkel ******

, OP is on an extension for being a spouse to a foreigner with an extension for employment. She needs to cancel her extension officially even after it's expired, same as the amin applicant (her spouse), and a fine will be applied if late to cancel.

@Ella ****

, you need to cancel your extension even after it has expired, along with paying a fine.

@Wenjing ******

, it's an online application. However, you need to be in that country as you have to upload proof of your being in that country.

You need to talk with the schools for details.

You need to cancel the current extensions with a termination letter (stating end of study on xxx date) from the current school at the immigration office. Then apply for new extensions with documents from the new school at the immigration office in the new province.

Depending on the current province office's policy, you may or may not be able to apply for cancellation in advance.

If the timeframe allows, you may change the school and get new extensions without leaving Thailand. Detailed procedures and timing depend on many factors, you need to talk with current and new schools well in advance.

You need TM30 receipt with the address matching your long-term lease for a 1-year extension in Bangkok, along with the lease agreement, owners' ID (signed copy of national ID & blue house book, or passport in case the owner is a foreigner).

They tightened the TM30 account approval process a while ago (it was mentioned on the system for a while).

If you can register a TM30 account with the correct address, it would be okay.

@Arnaud **************

, be aware that re-entry permit wouldn't buy any additional time. it expires at the same as the current stamp expires, and will be stamped in for the same last date with the current stamp..

As long as you apply for an extension for the same reason, it will be "added" to the current extension regardless of when you apply. It will be the same "until" date every year.

But,

If you apply for a different reason for Non-O based extension (for example, you apply for a new extension for retirement when you are on an extension for marriage to a Thai), it will be start on the day of application.

@Jon *****

, no, there is no medical reason requirement for parent over 50 to be on Non-O dependent on a foreigner with a long-term extension in Thailand.

The flight out of Thailand can be bound for any country.

Your first itinerary has to start from your country because METV can be applied only in your home country, and you must be in the country where the embassy/consulate is located as of the application.

The second and later itineraries can be from/to any country.
