Lloyd Turner sorry your are perfectly wrong and don’t know what you are talking about, the fact that she has departed Thailand does not automatically cancel the extension of stay!
The normal, and expected process, is for the foreigners to cancel the ED extension of stay BEFORE they leave Thailand - obviously in this case it didn’t happen as she expected to return...but the extension of stay MUST always be cancelled...so on return she must cancel it!
I myself, was outside Thailand when my previous ED extension of stay expired and on my return (with a new visa) I needed to go to immigration and obtain the cancellation stamp.
I was advised by Tod to do this, and in doing so avoided an overstay fine! Immigration confirmed I would have been fined if I had not done this - when I next reported to them!
Expire and CANCEL are not one in the same - it MUST be cancelled!
You should not give advice when you are simply guessing!
As Lloyd already said - you will have to apply for new ED visa again.
But I add one thing...when you return to Thailand, go straight to immigration (with a letter from your old school requesting cancellation) and cancel the PREVIOUS extension of stay! It does NOT cancel automatically, even if having left the country.
Not cancelling it won’t stop you from getting a new visa, BUT after you return to Thailand and next report to immigration they will see that your previous extension of stay based on ED was not cancelled, and you can be fined up to 20,000 Baht for overstay.
Yes, it does happen, as ridiculous as it’s sounds...so long as you cancel it on your return you will be ok!
In Jomtien, if that’s where you will be...you will need to file it twice...they are reasonably strict here...but you can even fill out the TM30 yourself and lodge it within the 24 hour time period..,very quick...only 5-10 minutes waiting and your finished and on your way
If you’re in a different area of Chonburi I don’t know 🙂
I would err on the safe side and get a new passport...it’s actually up to us to ensure our passport remains undamaged, or to replace it.
It will be very inconvenient, and costly, should entry to any country be denied and then be stuck in limbo until a replacement passport is obtained.
No one here can say it’s ok or not, only the immigration officer on arrival ... or your embassy, but I can tell you now they will also advise you to replace a damaged passport (as they can’t say whether an immigration officer of another country will accept it...it’s completely up to the discretion of the immigration officer)
