Today, I went o port at Detroit for Canada, I was refused to enter and sent back o us port, and showed my AP, passport and I94, bu he CBP officer did not stamp my AP, and record my information, ask me to apply for a visa to Canada, and then go to Canada agai, then they can process stamp on my AP. now I am going to apply Canada visa tomorrow morning.
so the question is: is there any negative effect on my status and my I-485?
