Then no. You should never use your national password again. Since your claim is based on persecution from your home government, using your NP will definitely cause you to lose your asylee status. Canadian immigration authorities have to stamp the travel document where your visa is stamped/attached/embossed. You can't show your visa on your NP then ask them to stamp your RTD. You will have to apply for a new Canadian visa using your RTD. Even after you get a GC, you must still not use your NP and will always have to renew the RTD until you become a US citizen.#1. No, I do not have a green card yet.
#2. Yes, is based on persecution from Government but I have never renewed my NP and I don't plan on traveling to my country of persecution.
