My husband and I have been married since March of 2005. We are currently in the process of filing the I485, which we first submitted in June 2005. Question we cross back and forth over the U.S. Canadian border many times a week because we are renovating a house in the US and living at a cottage in Canada...I work in NY and my husband has a seasonal business in Canada...usually we have no problem crossing....but legally what in the world should he be filling out so that he can continue to legally be crossing.. I often see that people can get turned down at the US border if they enter without a travel document and stuff.. Any advice?
