Balance transfers can take from two days to six weeks, depending on the card provider. This means you may have to make an extra payment on your old card to avoid any penalties or fees.
Balance transfers are made between issuers either through an electronic funds transfer or a balance transfer check. When you use a balance transfer check, it takes a bit longer because the check needs time to clear, just like when you deposit a regular check. Be sure to account for this when planning your balance transfer.
If you've opened a new card with an introductory balance transfer APR offer, you'll also need to wait for the issuer's approval before you can start a transfer. Depending on the approver, you can initiate the balance transfer immediately, or you’ll need to wait a couple of days to proceed.
