My b1/b2 visa expired went for dropbox and was asked to come for inteview, I went and was given 221G for to submit additional documents which I did through DHL. Few days later my passport and all the documents returned to me with another form stating that my application is undergoing through admistrative processing. My concern is that it has been more than a month, when I checked the status of my visa application it read " cased last updated 20 June 2018 and Ihave not been contacted in any form. Pls is the admistrative processing concluded. Thanks
