Relocation services provide the supports required by your move from one location to your destination home in a different country while removal services are basically the physical removal of your possessions from one location to another.
There are many things involved in relocation services, such as purchasing a new home in your preferred location, language, and cultural training, moving pets, bank accounts, medical procedures, etc.
You will also have to deal with work permits, finding a school for your kids, visa requirements as well as immigration services.
You will easily get help from international moving companies on these services, or they partner with other international companies to get these done for you most smoothly and easily.
