. Now you are just trolling.. At passport control you clown.. If you use an automatic gate it scans it too. And what part of US agreement with Mexico confuses you? What part of every.other country confuses you?
. USA and Mexico have a long standing agreement regarding what you just mentioned. If you exit USA to enter any other country your passport will be scanned by USA border control and the country you enter.
. Think about it... an expired passport is worthless. They will deactivate your old passport when you recieve a new one be it renewed or replaced. If you recieve a new one whilst overseas at a US embassy, they also do this prior to giving you new one. Will have new passport number rendering old passport void. All history will be transferred to new passport via the microchip.
. Also a passport is a federal document and belongs to your government, not you. Gives you permission to leave if they have no reason to not let you and permission to re enter.
. Yes. Australia has same system . The equivalent dept knows when you leave and will limit or remove any supplemental social security payments you recieve such as rent assistance utility bill assistance, etc. Unemployment benefits are stopped after a certain time too . They don't track you... but you will be flagged in your file that you have left the country and will be flagged again when returning. The whole purpose of the microchip is to know what country you are in.. First thing passport control in any country does is scan the chip in your passport to check your history and visa status. That's its purpose. Also massively reduced passport forgery. Days of fresh passport to hide travel history are over. Welcome to the 21st century.
. A little thing called a microchip in your passport... they , like most countries, know the moment you leave and the moment you return. All linked to govt services
. If it's a lump sum , I would use bank to bank using swift code. Multiple smaller amounts use other things like wise, remit, etc. You don't actually need to show international transfer evidence for 400k for spouse visa/ext. They don't care where it comes from. Cheapest way is in your pocket when you fly in, but exchange currency in Thailand, not outside . Better rate.
I got one of the last multi entries there last year 29th May. They stopped them 3 days later. 400k was still required . All e visa now and 3 month maximum.
