Over 400,000 Palestinian refugees and descendants live in Lebanon. They are not allowed to own property, and even need a special permit to leave their refugee camps. Unlike other foreigners in Lebanon, they are denied access to the Lebanese healthcare system. The Lebanese government refused to grant them permission to own land. The number of restrictions has been mounting since 1990. However, in 2010 the government of Lebanon removed work restrictions from Palestinians, enabling them to apply for work permits and work in the private sector. In a 2007 study, Amnesty International denounced the "appalling social and economic condition" of Palestinians in Lebanon.
