Israel signed a memorandum of understanding with the United States on Wednesday night as a first step to joining their visa waiver program. 

The agreement aims to ensure that Americans with Palestinian citizenship, whether from the West Bank or the Gaza Strip, are able enter and exit Israel and Palestinian territories freely, as well as move between them. 

The U.S. visa waiver program, which makes the process of travelling to the country significantly easier, requires that partner countries commit to a policy of "non-discrimination" toward American citizens. 

"The updated travel policies, which go into effect July 20, will allow all U.S. citizens to travel to Israel via all ports of entry, including Ben Gurion Airport.  This policy applies to all U.S. citizens, including Palestinian Americans on the Palestinian population registry," the State Department readout said. 

The U.S. added that it will "closely engage with the Government of Israel and monitor the implementation."
