A ‘snowbird’ refers to a person who migrates to warmer climates when the Canadian winter arrives, only to return once the snow melts. Of course, one does not take a long term move to a foreign country lightly, as there are many things to prepare for. An excellent resource, that I highly recommend is the published book by John Wiley & Sons, Inc:
“The Canadian Snowbird Guide: Everything You Need to Know about Living Part-Time in the USA and Mexico” by Douglas Gray.
There are more things to consider apart from the economics, such as obtaining health care abroad, property ownership and maintenance, security. The guide will help you get started with everything that you need, including what documents you may need for entering the US, how to ensure that everything will be okay at home while you are away, and how foreign laws and regulations will apply to you. Anybody thinking of escaping the winter chill should read this book before heading off worry free to the sandy beaches.
