Yes, you can! If you do not have all documents on hand and would like to upload them later, you can do so by saving and accessing the tracking link.
The tracking link will be provided through your email, or through your Flywire account (if you have created an account) under the “My Payments” section. You may also share this tracking link with any third party assisting to upload documents on your behalf.
However, please keep in mind that you will not be able to access your payment instructions until you have uploaded the required documentation.
