I met a cop recently, who was vaping a very big electronic cigarette. Asking him about it, he said he took it / confiscated it off some poor schmuck since they are illegal. TIT.
1) Up to 90 days is easy: Get a regular TR Tourist Visa, that gives you 60 days in Thailand and can be added another 30 days at any Thai Immigration office. 2) If you want / are ready to (briefly) travel neighbor countrires, you can do border bounces. You could make use of a Multiple Entry Tourist Visa or just another back to back single entry tourist visa (or even a visa exemption) then. 3) If you want to stay up to a year but are not yet committed to retire long-term: Look into the Non-Immigrant Visa (O-A) - available to Canadians, without the need to transfer money into Thailand.
There are several options to solve this. A fully refundable return flight ticket (which you could change of cancel once entered Thailand). A cheap throw away ticket by either bus or train into any nearby country. A borrowed return ticket (there is actual services in the internet offering that against a small fee). Make your pick.
Yes, 30 day visa exemption for French. Nothing to apply or present before checkin / arrival. If fully vaccinated, no need for test. If not: COVID test needed. And yes, return (or onward) ticket out of Thailand within those 30 days is needed as well (though might not always be asked for / enforced) at either the checkin counter or at Thai immigration.
An extension is not a visa. So choose the actual visa you entered the country with (or in rare cases changed to in country). If you entered without a visa / on visa exemption, choose that.
No. But do your math to find out if itβs worth the much steeper visa fee (and stricter application requirements) - or if single entry visa back to back are the cheaper and easier option.
IF your husband will have (permanent / long term) residency in Germany, he will be able to apply for a Thailand TR tourist visa through the eVisa system with the Thai consulates in Germany. For this to be applicable he would need to be "granted a residence visa [so any national visa, not a Schengen tourist visa] to stay [in Germany] for more than six months".
