An overseas constituency or overseas electoral district is any electoral district located outside of a nation-state's borders but which is recognized by the state's government as a district for the representation of its expatriate (and, technically, military) residents who live within the territory of another nation-state. Such constituencies are often organized in order to engage expatriate or diaspora voters who retain their citizenship.
The overseas constituency is considered different from intra-party primaries (organized and funded entirely by political parties or political party organizations with overseas offices) held overseas for expatriate voters.
Overseas constituencies may perform their votes at diplomatic embassies and consulates of their home nation-state, through absentee voting or through electronic voting (including Internet voting).
Polling for expatriate Tunisians took place in 80 countries around the world. France, Tunisia's former colonial ruler, elected ten representatives; Italy three; Germany one; North America and the rest of Europe two; and other Arab states two.
A 2012 draft law would allocate 10 reserved seats of Parliament to Lebanese expatriates abroad in time for the 2013 general election.
The establishment of overseas constituencies has generated concern among some governments over possible infringements to national sovereignty. Notably, the Canadian government of Stephen Harper in 2011 protested at the establishment of such constituencies covering the territory of Canada by France and Tunisia, and publicly declared that voting booths for the upcoming elections for both countries would not be allowed in Canadian territory. However, in 2012, an agreement was reached between the three countries whereby such booths could be located primarily in embassies and consulate offices. Canada was the only nation that opposed being included in the overseas constituencies.
