I don't know how much foreign currency you are talking about, whether it is public or private. If it is for private use, it should take five working days for ordinary banks to wire hundreds of thousands of dollars, and two days at the earliest, and the remittance of tens of thousands of dollars will be more troublesome. You have to go to the bank to provide foreign exchange source description and proof materials; If it is a business remittance, it will be even more troublesome. If it is a trade remittance, you need to declare the export receipt or advance receipt at the SAFE, provide the contract, get the verification form, and write it off after export before you can use the foreign exchange. Until the verification and declaration procedures are completed, the money will be stored in the bank's temporary account and will not be displayed in the payee's account book. It takes a long time to collect foreign exchange.

If private remittance is urgent, you can find Western Union or MoneyPay. If you have access, you can also find a special channel in South Africa, which is very fast.
