Hello house , I receive a mail from the Canada immigration , telling me I filled no instead of yes when filling my (imm5257)form which states have you been refused a visa or permit denied entry or ordered to leave Canada or any country , and they found out have been refused severally at the American embassy , they now said they give me the opportunity to respond affording me 7 days from the day I revived this letter and if not I will be refused . And also if found out that I engaged in misrepresentation in submitting my application , It will render me inadmissible to Canada for 5 years, please what am I going to do, and what’s my hope , but honestly I was just denied at the embassy on normal ground no serious offense.
