There are some speculations about the relationship between travel history and processing times but there isn't any concrete evidence. It's usually hearsayI am in the same boat. My AOR is 7th July and I'm still waiting. I also have visited more than 6 other countries including US.
I think that it depends on your travel history. The more countries you have visited, the more time it takes for them to process your case. I am suspecting this because my friends who applied after 2 months than me and have a really short travel history got their PPR last week.
Anyone else here thinks that processing times depends on travel history? It's just my theory so don't attack me
