You switch passports on the international flight, as far as domestic it's just for ID, there's no visa synchronization.

assuming you bought a re-entry permit?

One spouse can be the primary TV holder and can write a sponsorship letter for their spouse for the second application. Ideally you'll show financial stability, more than likely if it's a joint account a million baht would be satisfactory. The Canadian consulates are very responsive so I'd put your question to them and as far as the GIC I doubt it.

counting to 90 from the day you entered, or the day you did your last report, or reading the paper stapled inside your passport is hard. Persevere

Absolutely zero issue, thousands of people overstay by a day or two every week.

Passports don't matter you just need things like marriage licenses and birth certificates for dependents and spouses.

Get creative Julie.

Just do it at the airport instead of spending half a day at immigration and getting there and back. Allow an extra 20 minutes at the airport.

There is no certain time, but, immigration is cracking down on people using back to back visa exempt stamps, it also depends on which border you're using and either flying in or crossing a land border.
