I am visiting the USA with a B1/B2 visa, with a Kenyan passport. Do I need a visa to visit Canada and if I do, what are requirements and the process for me to be able to get a visitor's visa?
Kenyan nationals do normally require a visa to visit Canada.
To apply for a visa, you must show evidence of your legal status in the territory where you're applying.
In your case, proof of immigration status will be
- the visa you used to enter the US
- the stamp you received when you entered the US, and
- a print-out of your I-94 record, for which you'll need to visit http://i94.cbp.dhs.gov.
Other requirements are substantially the same as for your B1/B2 visa, or indeed for any visitor's visa. You must have a reasonable purpose for your trip, you must have enough money for your trip, and so on. These requirements are also covered in the sources cited above.
