Hello, I have a CoPR and am currrently residing and working in the US. I plan to visit Canada in the next month or two and get my PR activated. After that can I apply for US visa H1B stamping in Canada as a Canadian PR and become eligible for a dropbox? I had my H1B stamped first time from India and have more than 24 months left on my current H1B. The risk here is that currently I do not have H1B stamped on my passport, and I'd be leaving US with the hope that I'd be able to get it stamped in canada as a PR with dropbox option and then fly back to the US.
