the copr...is the white sheet he will get at the embassy when he gets his visa...when they get their visa they get a legal size envelope with their passport in it and 2 8 x 14 pieces of white paper....the immigration officer at the embassy will hand out the envelopes and tell everyone to check over the white sheets carefully because that is what they need along with their visa in the passport......when they arrive in Canada the border people will keep one copy and the other copy your husband has to keep.....they will go over the information with him and have him initial certain parts of the form....KEEP THIS FORM....this is what you need to get your SIN; bank account...health card.........very very important.
The B4 form he should just put down the contents of his suitcase i.e. 4 pairs jeans; 4 cd's; 6 t-shirts; this is for suitcase only or if he has other luggage following later....most cubans don't!!!! He will also have to fill out the standard Customs Declaration form on the plane....if he brings rum/cigars/cigarettes he has to declare those on that form!!!
Hope that helps Emily!!
