Hi, guys, I am pregnant and I want to help my mother to apply for a visitor visa. I'm so confused that IRCC portal only let me upload one file (docx.) last week and others all failed, and it shows "We don't accept this file format. Try again using one of these accepted formats: .tiff, .jpg, .png, .doc, .docx and .pdf.". But I definitely tried pdf, jpg and docx, and make sure each file is below 2MB. I didn't find anyone who has the same problem online. So what is the problem? Is it right to apply from IRCC Portal for a visitor visa? Thank you very much for your guys' supporting!
