Visiting Canada to get H1-B visa stamping - do i need canada visitor visa

[himantay]

i heard that i could just travel to canada with my valid i-797 and valid i-94 to appear for an interview at the US consulate in canada. Do i need a canada visitor visa at all? is there something like a 30-day rule that would apply to me?

30 day rule is for people entering into US from Canada.
