I was directed to use the PR Portal to submit my photo and confirm my address. It asks for cropping the photo to make the face look bigger, but it says that the officer can do it on behalf of me if I am not sure about how to use it. I was worried that cropping my change the photo in a way that it violates their specifications so I just didn't crop it to fit it into the circle. Is this ok to do? Also, the portal turned the pic into black and white. Does it delay the process in any way although they say they can still do it for me?
