Carolyn, Just traveling to Bulgaria for  2 weeks to get my In-Laws Visas to the US, I got to see the shady process of getting visas in Bulgaria for US visits. Since my In-Laws were denied, I question Bulgaria's goal to be accepted into the US Wavier Program.  If a 78 year old woman is denied due to the Embassy believing she going to to the US to work, what hope does everyone have?  Good Luck......
