After reading this. I can confirm. Following your instructions, I set up an international account in iBanking. That took 2 days for approval. Receiving account directly to Schwab CitiBank acct., (then forwarded to my name). Approved. I will test a small transfer first before sending the rest.
While doing this, I discovered a previous international bank account I set up over 13 years ago to a small U.S. credit union (which only has ACH number). This acct. only has my name on it. So, now I have 2 approved accounts.
In the BB mobile app, it appears you can do international transfers. Bottom right corner of the app "more services". International transfers are located there. However, the "personal expense" app limit says 1 million bht, while iBanking says 40,000USD which is about 1.4 million bht.
