Put the purpose in writing
More travel flexibility, another place to live and a longer-term plan for your family are different goals. Rank yours before looking at programmes. The useful brief is specific about what you want to change.
Separate the questions
Citizenship, residence permission and tax treatment need separate consideration. Ask qualified advisers to explain how each applies to you rather than assuming one document answers everything.
Investigate what is already available
Family history, existing residence and future relocation plans may all be relevant. Collect the facts you already know, then ask an appropriate specialist what is worth investigating.
Check the people and the process
Before paying, establish who is authorised to handle the application, which authority decides it and what the complete cost includes. Ask what happens if the rules change or the application is unsuccessful. A proper process should be clear about uncertainty.
