Thanks so much I already spoke to my lawyer and we are working on itJust apply for the RTD and surrender your passport. You should include a letter explaining why you renewed your passport and clarifying that you have not used it to travel back to your home country. They can easily verify this with the stamps on your passport.
What you did is not forbidden or illegal, but you will have to explain why you did it. I assume that you didn't apply for an RTD because you didn't know about it... if that's the case then say so.
Obviously, my assumption is that you have not traveled back to your country.
If the government decided to take your PR, they would have to prove that by renewing your passport you were seeking the protection of your home country government... That is not easy to prove.
If you want more reassurance then you should talk to an immigration lawyer, that will give you the peace of mind that is hard to get by reading anonymous posts on an online forum.
