My husband and I are getting ready to apply for permanent residency through family sponsorship. He is a Canadian citizen, and I am an American citizen. I am currently in Canada with him (as a visitor at the moment). I was looking through the document checklist for the PR application and noticed that they want to see a stamp in your passport of your most recent entry to Canada. I entered by land (at the border crossing in Niagara Falls, ON) and did not receive a stamp in my passport. What should I do? Has anyone else experienced this? Will I have to leave and re-enter? I am afraid that by doing that I might be denied re-entry (I am just paranoid).
