You can use the money as soon as you apply for a credit card. Once you have just applied for a credit card and successfully activated it, you can use the money to apply for a cash advance if there is a limit in the card.
The credit card you just applied for can be used for cash advances. The maximum cash advance limit is 50% of the credit card limit, but there is a temporary limit on the card, and the cash withdrawal limit will be increased. There is no minimum repayment for cash advance, and it cannot be paid in installments. It can only be repaid in full. This method of borrowing has high repayment pressure, so use it as little as possible.
