Quick question—this might be a dumb one, but why would they let you apply from KL? Wouldn’t the embassy require you to apply from your home country? And if you travel to KL, wouldn’t you need to show the bank statement from your account in your home country?
Best of luck, bro! You might actually be one of the first, or even the very few, to apply for the DTV from Pakistan. I checked with the Thai Embassy in Karachi, and they mentioned that they haven’t received any applications for the DTV yet.
