There might be a small issue. The under consideration period is used to consider if your meet all the requirements, one of them is if your marriage is de jure and de facto.

This is done by a visit to your address and can not be done if you spent the time in Korea.

So the worst thing in life is going to happen, you have to discuss with the officer if you can leave and can use a re-entry permit in this period.

Good luck.

Your old passport is invalid to use, you need to use your new passport and fill in the number on the notification form. You need to transfer the stamps before you can register your 90 days of stay.

You signed but you did not follow up what you signed. It could bite you in the a.. when you try to do this again, this counts for Immigration as well as Ministry of Labor.

Be aware what you sign, telling I did not know does not count when your signature is under this text.

The form you signed at Immigration as example:

Talk with your employer

I guess you like to be there to, so you must have a long stay solution, apply for her to be dependent on a foreigner with long stay.

What happened is that the officer you handed over the documents is very capable to check if everything is in order but does not have the authority to stamp your passport. All documents are now at a supervisor to consider, it is rear that during that period an application gets denied,.

You go back on 31 October and normally get the visa and a new 90 day stay or in worst case scenario a stamp application not approved and 7 days to leave the country.

Yes, keep on going. There is no limit other than an employee at an Embassy who decide no more abusing this type of visa or an Immigration Officer trying to do his work.

You might opt for the visa that fits your purpose of stay and get 1 year Extensions in Thailand to avoid the travel and harrasments at consulates or borders.

Get the retirement visa before you make your way into Thailand as that gives you 90 days of stay and relaxed time to sort out in 30 days the deposit for a 1 year Extension of Stay, rather than first running around to get a visa.

yes, he can use that re-entry permit to come back and get the same date as the Admitted until date stamped in his passport.

OP does not have a visa but an Extension of Stay which she like to call a visa.

a Visa can not be cancelled, an Extension of Stay needs to be cancelled.

And that is why it is important to understand what is stamped in your passport to give correct advice without seeing the passport.
