You need a minimum of 800k not 700k. Wether or not your wife can piggyback on your extension depends on where you apply for the extension. I know from experience Chiang Mai allows that but other immigration offices might not, also make sure the 800k is NOT in a joined account.

@Ron ******

thanks again for another invaluable advice, where would this group be without members like you.

Thanks for your comment, not very helpful but thanks nevertheless.

I am in Chiang Mai, have a TM 30 slip in my passport, stayed outside the province in hotels on several occasions, never reported this to immigration and (so far) don’t have a problem with 90 day reports or visa extension.

Corruption in Thailand? Really? You got to be kidding me!

One addition to Tods advice: If you surrender yourself to the authorities you will probably be able to still clear overstay without a ban however if you get arrested or caught otherwise it could result in a 5 year ban so you might want to get this sorted ASAP.

If your husband is over 50 it’s relatively easy to get an visa/extension of stay. This can be renewed yearly, you as his wife can get a dependent visa/extension of stay. However working IN Thailand is prohibited. You state he flies in and out of the country so should be no problem for him, your online business might be not within the rules however here in Chiang Mai there are literally 1000’s if people working online from Thailand and the vast majority doesn’t have a work permit. It’s still a risk though.

The main problem would be with the immigration offices that require this form for your extension of stay.

After the Visa is issued you have 3 months to use it and enter Thailand, on entry you will be admitted for 60 Days.

Between 14 and 7 days before due date you can do your 90 days by post, you don’t have to send your passport just copies of main page, visa, arrival card and tm 30. Send them together with your last original 90 day report, a self addressed envelope and filled in tm47 form to:

Notify 90 Days

CHIANG MAI IMMIGRATION

Building A, G Floor

Promenada Resort Mall

192 - 193 Tambon Tasala,

Amphur Muang, Chiang Mai

Have done this several times, i use EMS to send and just a normal 3 Baht stamp on the self addressed envelope. It takes about a week before you receive the new passport slip.
