<p>Anokhi, I faced the same problem. Originally i got an appointment on sep 6. Go to this page <a href="http://www.ttsvisas.com/Homepage.aspx%5B/url%5D">http://www.ttsvisas.com/Homepage.aspx</a>
You will see a Modify/cancel appointment link. Log in. Appointment slots keep changing throughout the day. I was able to get an appointment on july 18. If all else fails call the TT services.<br>
Hope this helps</p>
