Hi, I'm Thai student, holding I-20 VISA of the US. I'm living in Boston now. I need to visit the Niagara Fall for a few days but I'm not sure whether I need to get Canada VISA before going or not. I asked one of my Thai housemate, who's been to the Niagara Fall before, and he said that I need to get Canada VISA. However, it's been a little bit confusing because I asked one of the consultant in my school, and she said I don't need to get a VISA to go to Canada.

Could you please help me answer this? It's getting serious because I have to go to New York to get that VISA if I need to.

As international student, if your country is not listed on Canada's visa waiver program, you need to obtain a visa.
