Anuradhapura Municipal Council is a member city of World Tourism Cities Federation (WTCF). Annual world summit of WTCF will be held in Los Angeles from 17-21 september 2017 and received invitation from Los Angelese Tourism & convention board to attend the WTCF world summit. The all expences should be born by WTCF.
I applied B1 visa twice and both applications refused under section 214(b).

Could I ask for reasons to refuse my visa or to whom I can appeal?
