Now the interview sending process had been changed. Once your interview is scheduled, you will get a electronic notification from the KCC. It will be shown to you in the website, where you had submitted your online visa application form.
Also take note that the American dv lottery used to close every year on 30th September for the current fiscal year program.
Go to that web site enter the confirmation number and other details.
If you get an Error message, means that your interview is not scheduled.
The interview letter will be shown in the screen.
Get a printout of it and follow the instructions given there.
On the given date go for the interview with the processing fee and with all the important documents and with your passport.
Include your winning notification and the copy of the interview letter in your documents.
Don't reschedule the interview date as you may lose your chance.
The program offers visas on the first come first serve basis.
So if you reschedule your visa interview there will be no visa allocated to you when you come for it.
