It depends. That is wire transfer. Credit card can be very fast. There are other like Skrill, Neteller, and many other ones that can be fast. But  the cost can be high and some are restricted, unlike wire transfer.

In the worst case, bitcoin transaction can take up to 14 days and it may drop from mempool instead. If you use non recommended wallet that keeps on rebroadcasting the unconfirmed transaction, it may take more than 14 days and it depends on how mempool congestion is. Also the purging can become more than the fee rate used and your transaction may be dropped from mempool.

But bitcoin transactionis cheap and if the right fee is used confirmation can be in less than 10 minutes or more than 10 minutes. Although, if comparing bitcoin transaction and international transaction, bitcoin transaction is far more reliable for faster transaction with low fee. If comparing it with wire transfer which is not restricted in most countries, bitcoin is far better.
