This explains my curiousity

Which is best Malaysia bank to bank in U.S. check?

Generally, the exchange rate and check processing time are about the same among local banks. The exchange rate is between 3.77 to 3.78. The time to process the check will take about one month.

According to the thread I started in WebmasterMalaysia.com and readers’ feedback, here is the comparison of US check processing fee(per check) between different Malaysia local banks. Not sorted in any order.
