The Pakistan-to-Congress story
Pakistan has produced 1 naturalized citizen who went on to serve in the US Congress — 0 in the House of Representatives and 1 in the Senate. 1 is currently serving, while 0 have completed their congressional careers. That career began in 2017, during the modern Congress. All of them represented MD in Washington.
Pakistan reserves the ballot for its own citizens: non-native-born residents cannot vote in any election there, no matter how long they have lived in the country. Specifically: Only Pakistani citizens may vote. Non-citizen residents have no voting rights. Pakistan does not recognize dual citizenship from most countries.
Every Pakistan-born member tracked here has served as Democrats. That produces a striking asymmetry with the United States, which not only naturalized this member but then elected them to help write federal law. A naturalized American who returned to Pakistan would have no such political voice there. Across the full history of the US Congress, Pakistan ranks 35th of 38 tracked birth countries, accounting for 1 naturalized-citizen lawmaker.
Put plainly: a person born in Pakistan can be entrusted by American voters with a seat in the US Congress, writing federal law for hundreds of millions of people. Yet the same person, if they returned to Pakistan, would be barred from casting even a single ballot there. That is the contrast this tracker exists to surface.
