A second residency is a right to live somewhere other than the United States. You may want that right in place before you need it, as an option to test a country, keep a door open for family, or have somewhere to go if circumstances change. Several programs let you secure it before you move, while your home, work and accounts stay where they are. The useful starting point is what you want the option to do, and what it will not change.

This is general information. Your CPA and counsel confirm the details for your case.

What a second residency changes, and what stays the same

A residence permit is permission to live in another country under that country's rules. It is not a new citizenship, and holding one is not, by itself, a way of losing US citizenship. Under 8 U.S.C. 1481, a US national loses nationality only by voluntarily performing a listed act, such as naturalizing in another country after age 18, with the intention of giving up US nationality. 1

Your US tax position does not move with you either. IRS Publication 54 says that as a US citizen or resident, your worldwide income is generally subject to US income tax regardless of where you live, and the same filing requirements apply. 2 A residence card abroad adds a second set of rules to understand. It does not replace the first.

What the numbers show, and what they do not

Figures on Americans holding residence abroad are published country by country. Portugal publishes one of the clearer ones. AIMA, its migration agency, counted 14,126 US nationals in Portugal's resident foreign population in its 2023 statistical annex and granted 4,823 residence titles to US nationals that year. 3 Its 2024 report counts 19,258 US nationals at 31 December 2024, with 4,941 residence titles granted during 2024. 4

Read the larger jump carefully. AIMA's 2024 resident figure also includes regularization cases in progress and authorizations under specific legal instruments, so it is not a like-for-like comparison with 2023. 4 The steadier signal is the residence titles granted each year: thousands of Americans a year in one European country, under rules that keep shifting.

Why timing matters: program terms change

The strongest reason to plan early is that residence programs are rewritten, sometimes with short notice.

Spain's Organic Law 1/2025 emptied the investor provisions of its entrepreneurs law, including the residence visa for investors, with effect from 3 April 2025. 5 Its transitional rules let applications already filed be decided under the old rules, and kept existing investor visas valid for the period issued. 5 Applicants who had filed before the change were treated differently from those who had not.

Portugal's Law No. 56/2023 ended new investment residence applications based on real estate purchases. 6 Panama rewrote its program in September 2026. Executive Decree 17 replaced the Qualified Investor regime of 2020. 7 Panama's Ministry of Commerce and Industries describes the new minimums as $300,000 for a new, first-sale property and $500,000 for a second-sale property, with Panama's currency at 1.0 to the US dollar in the Treasury's reporting rates. 8, 9

None of this predicts the next change, or how it would treat you. It shows that the terms on offer today are not permanent. A decision you keep postponing is a decision made under whatever rules apply later.

A long stay is not the same as residency

Some countries let you spend extended time without a permit. Georgia, for example, allows US citizens to enter and stay without a visa for one full year. 10 That is a useful way to test daily life, banking and costs before you commit. It is a visa-free stay, not a residence permit, so it does not give you the status a Plan B is meant to secure.

What this means for you

Treat a second residency as a decision with three parts: the country and permit, the money or investment it requires, and the reporting that follows you as a US person. Settle what you want the option to do first. Then compare programs on their current terms, their upkeep and their exit routes, rather than on headlines.

What to do this month

  • Write down why you want a second residency and how you would use it while you still live in the US.
  • Shortlist two or three countries and confirm each program's current terms, renewal rules and presence expectations with qualified counsel.
  • Ask your CPA how any investment, account or entity tied to the permit would be reported.
  • Keep a dated file of each program's terms, so you can see what changed if you apply later.

Common mistakes to avoid

  • Assuming a residence permit changes your US citizenship or US tax filing.
  • Comparing countries on a headline price instead of the full conditions and upkeep.
  • Treating a long visa-free stay as if it were residency.
  • Relying on old program terms after a country has rewritten its rules.

The FNC angle

A Plan B works when residency, banking and ownership are planned together. FNC starts with what you want the option to do, then looks at the residence routes, the banking you would need and any structure the investment requires. One of FNC's completed engagements combined a Panama SA company and residency card with a Georgian account. Your CPA handles the US tax treatment, and qualified counsel confirms the immigration terms. The aim is an option you understand fully before you rely on it.
