Do we need Canada visa for 2 days trip from Seattle?? thanks!! aon2007-04-22 05:37:12

hi all, we have two people here, one holds H-1 and another has green card, do both of us need visiting visa to Canada for a two days trip from Seattle? or H1 holder needs but not green card holder?? also does anyone know if we could apply visa at the port of entry of canada?? as we don't want to spend one day to wait to apply visa at Canada embassy in Seattle. or does anyone know what is the quickest way to get Canada visiting visa???? your answer is greatly appreciated.

Thanks a lot.

GC holder doesn't need a Canadian visa,but H1 does

thanks very much to xiaobaitu
