Is it right the alpha consultency for our career in calpine group Senegal?

Dear Asif, i too recieved the same offer from Alpha consultancy to be ociated with CALPINE GROUP-Automotive. I am in dilema whether it is a fishy one as they are asking around 1500$ for visa processing and also the salary what they are offering is very very high which even engineers in US doesnt get. Could you let me know the progress from your end so that i can think about it.
