Ans. The main use of ACH (Automated Clearing House) in the United States is for domestic payments. Although a small number of banking institutions may provide international ACH transfers, they might not be the most practical choice for cross-border payments. Wire transfer is the most common technique for sending and receiving money internationally. Compared to ACH payments, wire transfers are quicker and more secure, and they allow you to send money in other currencies. Though generally speaking, wire transfers are more costly than ACH transactions. It is a good idea to speak with your bank or financial institution before transferring money abroad to learn about the alternatives and potential costs.
