RHB MCA : It's possible to receive foreign currencies (USD inclusive) from a local MCA into RHB MCA, provided the sender & receipient names are the same. It is a TT transaction which may incur sending bank and/or 3rd pary correspondent bank charges. Apparently, RHB MCA foregin currency outgoing transfer to a local MCA is not allowed.

Wise MY : It's possible to transfer foreign currencies (eg. USD) to a Malaysia MCA, provided MYR is involved, ie. you "convert & send" Wise MYR --> USD into local MCA. The fee is high !
