If you wish to retain your U.S. citizenship you will need specialized financial planning and counseling. Your U.S. citizenship means that you must navigate a very complex additional layer of rules and regulations.
One of our core missions at US Taxation Abroad is to provide you with the life, investment and retirement counseling that only U.S. citizens require.
