I was properly screwed by immigration4us.
I have applied from their website for US Visit from UAE. They asked me to pay 165$, i was under impression that it included MRV fee as well. I surprised after receiving email from them as below.
"Please note that the charge of $165 for the visa service does not include the MRV Visa Fee that needs to be paid to the Department of State"
Simply they copied all the info from their site to actual trusted Gov site by charging $165.
Which is unfair at all.
