Isn't the idea that you're actually not in Thailand since you have to apply from outside the country? So, my assumption would be, no one cares about lease or TM30, no? I might be wrong, just from what I understand.
I won't show a lease or TM30 since I'm not in Thailand. 🙂
It depends on your bank I guess. But every bank I've ever been with allowed me to download my current statement until today (well, every bank after the internet was invented).
Are you suer you cannot do this? If so, I'd just wait until the beginning of the month but it seems bothersome. 🙁
From my email correspondance with them, that's all you need. I even sent my documents via email and asked if that's fine and they said yes. I'll probably go next week myself (to Taipei - I live in Kaoshiung at the moment).
Did you apply in Taipei? I sent them my bank statement via email, asking if it's fine. It was literally just for the past three days, showign >500k THB and they said it's fine. 🙂
