The normalization of Tehran's ties with Washington, as many believe, can be further hampered by the US Visa Waiver Program, which imposes some restrictions on foreigners intending to visit the US.

“I believe the HR 158 Bill [the US Visa Waiver Program], which is now a part of an omnibus budget bill considered by the US congress, is partly designed to prevent Iran from benefiting from the JCPOA [the nuclear deal],” Hooshang Amirahmadi, the president of American Iranian Council, believes.

Further speaking on the issue, Amirahmadi told Trend Dec. 16 that the move will indeed impact Iran’s economy.
