5 years ago, Malaysia bank account does need all these crap.

They won't call you. The MY officer which handle you will email you asking you to submit the form.

Current application. Let me tell my story.
1. My application was submitted on Dec.
2. Check with Maybank SG by Jan (1 month later)
3. Told me they never received. Told me to check with Maybank MY.
4. Checked with Maybank MY (they didn't call me/email me anything). Apparently Pos Laju sort of "lost it"
5. It was never even sended according to Maybank MY as the details are not completed (Maaybank MY fault    )
6. Resend.
7. Within 1-2 week received by Maybank SG as they email my officer asking for FACTA form (income tax from by the US)
8. They got back to me. Told me they don't accept emailed copies. Told me to submit hard copies to Maybank MY

Not within my justification. It was maybank part. I have no say in which courier they use.
