I’m from South East Asia too. Which country you want to go? I suggest more convinent country like Japan or Korea. At least they’re safe. Budget wise 2-3k usd per month is enough.

Taiwan internet is the best and it’s cheap. Food is cheap as well. Train system is good. I suggest you go Taiwan first to adapt your new job.

I work abroad and remotely but 5-6 hrs max per day
