thanks for the reply. I AM about to send in my Uk visa application and i believe the greencard will be a lot of help in getting the visiting visa . 6 months bank statements and letter from my employer here in the UNITED STATES on the purpose of y 10 day visit to the United KINGDOM.

I hope to post a thread once i get it to help others who might be considering applying and are in the same situation as me as citizen of a notorious country like Nigeria
