Acceptable uploads for proof of income (in PDF file format) are as follows: payslips, employment offer letters, gov't benefit award letters, child support summary printouts, monthly bank statements, etc.
*If your employer uses an independent payroll service that requires account login to access your payslips, then oftentimes you must "Print to PDF" and save into your device. Otherwise, the file that you upload will prompt for your password
Acceptable uploads for proof of identity are: valid State ID/DL, US Passport or US Visa (do NOT upload SS card or birth cert.)
** If you receive an error message stating that "file size is too big/large", then some workarounds are to reduce the resolution or clarity of the image and/or use the "crop" feature to remove all empty space around an image.
