The United States has no official count of how many US citizens live and work overseas. ACA's independant reserach by ACA Global Foundation and the Federal Voting Assistanc Program (FVAP) counts the community (military included) at between 6 and 7 million Americans. ACA's recent research estimates the non-military size of the community to be 5 million. 

US citizens living outside of the United States are sometimes referred to as Americans abroad, Americans overseas or "expatriates." Although US citizens live outside of the United States they are still US citizens; they can still vote in federal (and some state) elections, they still pay taxes and they still form part of the United States population.

Despite this, US citizens living and working abroad face a range of difficulties and challenges that are unique to them, and many of these problems are exacerbated by tax legislation and regulations.

Below is a brief overview of the problems facing Americans abroad. It is intended for US policymakers and those who are interested in learning about the issues and concerns facing US citizens living and working abroad.

The United States taxes citizens on the basis of citizenship (Citizenship-based taxation CBT), rather than on where the income is earned, often referred to as Residence-based taxation (RBT). This makes the United Statesone of only two countries in the world to do so. This means that Americans are taxed on their worldwide income regardless of where it was earned, where they live and whether they have already been taxed on it.

General Compliance and FATCA and FBAR

US citizens are required to file an annual tax return regardless of where they live if they meet certain thresholds.  They are also required to report all foreign financial assets over a certain value threshold along with their annual tax filings (as a result of the Financial Account Tax Compliance Act (FATCA), passed in 2010), in addition to filing an additional bank report form, a Foriegn Bank Account Report (FBAR).

Voting & Representation

Not all US citizens living overseas are able to vote, in particular those who were born overseas and never lived in the United States. Although a majority of Americans overseas are able to register and vote, their voice within any one Congressional district or State is limited due to the size of the constituency.  US citizens abroad lack "direct" representation, unlike many other countries which have a representative in government that directly represents the interest of its citizens living abroad.

Social Security 

Currently Social Security services are provided through the Federal Benefits Units (FBU) located in US Consulates and Embassies. throughout the world. With more and more individuals coming into compliance and needing assistance with Obtaining or reclaiming Social Security numbers and with questions on their benefits, the Social Security Administration needs to expand its out-reach and provide more direct assistance. US citizens working abroad also encounter difficulties applying for US passports, and can have their passports revoked for tax delinquency.

Healthcare & Medicare

Medicare benefits are not dispensed to citizens outside the United States. US citizens who are eligible for Medicare benefits and live overseas can only access these benefits if they return to the United States for medical care. Premiums are increased for those who sign up later than when first eligible, and some American health insurances require the insured to pay Part B premiums even when living abroad. This encourages citizens to travel back to the US for expensive treatments, which would cost far less in their countries of residence.

Every year about 60,000 children are born overseas to a US citizen parent. Of these, 90% acquire US citizenship at birth while 10% do not. These are children born abroad who are not able to claim citizenship because their parent or parents have not met the “residence” and/or “presence” requirements. The right to a nationality at birth is one of the most fundamental of human rights, as it opens the door to membership in our society and all other related rights. It is obvious that 6,000 children each year deserve better treatment.
