Most of the people working on the hundreds of tea plantations that dot Sri Lanka's picturesque hill country are descended from ethnic Tamils brought from India between 1820 and 1840 when the island was under British colonial rule. Although these people, known as "Hill Tamils," have been making an invaluable contribution to Sri Lanka's economy for almost two centuries, up until recently the country's stringent citizenship laws made it next to impossible for them to berecognized as citizens. Without the proper documents they could not vote, hold a government job, open a bank account or travel freely.
The Hill Tamils have been the subject of a number of bilateral agreements in the past giving them the option between Sri Lankan and Indian citizenship. But in 2003, there were still an estimated 300,000 stateless people of Indian origin living in Sri Lanka.
Things improved markedly, in October 2003, after the Sri Lankan parliament passed the "Grant of Citizenship to People of Indian Origin Act," which gave nationality to people who had lived in Sri Lanka since 1964 and to their descendants. UNHCR, the government of Sri Lanka and local organizations ran an information campaign informing Hill Tamils about the law and the procedures for acquiring citizenship. With more than 190,000 of the stateless people in Sri Lanka receiving citizenship over a 10-day period in late 2003, this was heralded as a huge success story in the global effort to reduce statelessness.
Also, in 2009, the parliament passed amendments to existing regulations, granting citizenship to refugees who fled Sri Lanka's conflict and are living in camps in India. This makes it easier for them to return to Sri Lanka if they so wish to.
