Do your research. Because you are crossing an international border there are some things you will not be able to bring with you during your move. The Internet is a valuable search tool to locate a list of items that are banned from crossing international borders, such as explosives, plants and produce. Make note of these items and be sure to exclude them from the items you are moving.
Pack and carefully label your belongings in boxes. Use a permanent marker to detail on the outside of the box what the contents are. This helps in the event that the border patrol needs to examine the contents of any of your boxes as you cross the international border into the United States and again at the California state border.
Since California is a heavy agriculture state, there are extra rules in place for plants and produce so bugs and other pests will not be transported into the state.
Keep all documentation with you in the cab of your vehicle or moving truck. This helps speed up the verification process at the border. You need passports for any children or adults traveling to California from Canada, a Canadian birth certificate to prove residency for any infants traveling with you, proof of your relocation to California, such as the lease or deed to your new residence or a letter from your American employers, as well as veterinarian records for any pets traveling with you.
Consult your veterinarian before traveling to make sure your pets will be allowed through the border crossing. If you are not sure, seek guidance from border crossing officials before moving. You also need valid copies of any United States work permits or visas required by your occupation.
