At present, the more acceptable method is to get a credit card that can be settled freely in multiple currencies. Even if you deposit RMB, you can pay by credit card in the United States.
In addition, the bank can solve the problem, go directly to the bank, get the foreign exchange purchase order, fill in the dollar value you want to remit, and remit it to the account. You only need to settle RMB (handling fee+money converted into dollars) for the bank at one time.
Recently, Alipay has also launched a foreign currency settlement business, which can also be done through Alipay.
