Refugees in Lebanon, 2019

More than 1 million Syrian refugees are registered with the United Nations High Commissioner for Refugees (UNHCR) in Lebanon. The government estimates the true number of Syrians in the country to be 1.5 million.
Lebanon’s residency policy makes it difficult for Syrians to maintain legal status, heightening risks of exploitation and abuse and restricting refugees’ access to work, education, and healthcare. Seventy-four percent of Syrians in Lebanon now lack legal residency and risk detention for unlawful presence in the country. In March, Lebanon lifted some restrictions to residency for Syrian refugee children age 15-18.
In 2017, Lebanese authorities stepped up calls for refugees to return to Syria and put pressure on UNHCR to organize returns despite the ongoing conflict in Syria and well-founded fears of persecution held by many refugees.
Lebanese authorities estimated that from July to November, between 55,000 and 90,000 refugees returned to Syria under localized agreements not overseen by UNHCR. Refugees have said they are returning because of harsh policies and deteriorating conditions in Lebanon, not because they think Syria is safe. On November 3, the Minister for Refugee Affairs said that about 20 refugees, including at least 2 children, have been killed by Syrian regime forces since their return.
Municipalities in Lebanon have forcibly evicted thousands of refugees in mass expulsions without a legal basis or due process. Tens of thousands remain at risk of eviction. 
In 2018, Lebanon continued to impose entry regulations on Syrians that effectively barred many asylum seekers from entering Lebanon.
There are also approximately 174,000 Palestinian longstanding refugees living in Lebanon, where they continue to face restrictions, including on their right to work and own property. In addition, approximately 45,000 Palestinians from Syria have sought refuge in Lebanon.
