The IRS states that they issue most refunds in less than 21 calendar days from the date the return was accepted by the IRS. This is in a normal year and is a target only--not a guarantee.
Then it depends on the U.S. and Filipino postal services to get the check to you.
You can check the status of your refund by going to the IRS Refunds page. You can click on the Check My Refund Status link or download the IRS2Go app for your mobile device. Wait at least 24 hours after your return has been accepted.
