Same here. AOR by email and SA by regular mail. I'm living in Europe and it took 10 calendar days for me to get the letter (from when it said decision made) and when I get mail from home it usually just takes 4 working days. So don't stress out too much.bartjones said:I wouldn't be too concerned. I also got AOR by email and sponsorship approval by regular mail. Made no sense to me since they obviously had my email address, but it doesn't mean you have anything to worry about.
