Hi I have been trying to apply for an offcampus work permit for a few days now. I have uploaded all my documents fine except for my application which continuously give me an error message: " Unable to validate your documents at this time please try again later". I printed the last page after validating, and signed it. (the page with the barcodes). Then I submitted it as a .pdf file. However it is still giving me this issue, it has been days now. Any suggestions?
