Moving from Canada to the USA is not all that difficult. There will be responsibilities you will be required to undertake. Among the most important things not to overlook would be the registration of your car. When you move to a new state, you will be establishing residency in that state. Your residence will be your official mailing address. Based on this residence, you will provide a physical address for your driver ‘s license. This physical address will also be where you will commonly register your car. (You may be able to register it at a different address within the state such as a business address) The car will have to be registered within a set amount of time from moving to the state.
