Yes, it's a radical step. However, if you're a U.S. citizen, you can make nearly all of the preparations for a possible future expatriation without permanently leaving the United States. This is a four-step process:
- Phase 1. Relocate your assets from the United States to other jurisdictions, preferably where the assets won't be taxed.
- Phase 2. Identify foreign countries where you would consider living,
- Phase 3. Obtain a suitable second passport
- Phase 4. Expatriate – give up your U.S. citizenship and passport
