Canada - Criminal Records

If you have a criminal record, no matter how minor or how long ago the offence, you may be refused entry to the United States or encounter problems in transit through its airports. A pardon issued by Canadian authorities is not recognized for purposes of entry to the U.S. If you have a criminal record, you should contact the U.S. Citizenship and Immigration Services (USCIS) before your trip. You may apply for a waiver of ineligibility, Form I-192, "Application for Advance Permission to Enter the as a Non-immigrant."
