Sarah. My experience has been the opposite. I am treated with more respect because of my age, as that is a Thai ‘trait’. Obviously everywhere could be different, I suppose.
Agree that you should forget about permanent residency!
. I believe you but would you want to start a new life, buy house/car then get blacklisted, never to return. Things are getting more tightly checked nowadays. I know loads of backpacker kids ‘winging it’ but they are not here longterm.
. You need a work permit to do anything, mate and to get one of them, you need the correct certification. Like everything in this crazy corrupt country, there are always ways around problem if money is involved.
. Agencies take teachers without sometimes but in the long run, it’s not foolproof. All jobs for government schools will need a degree. I teach adults in a Uni since 2011 without one but every year it’s getting increasingly difficult. Suggest you think about degree certificate.
