Hi lb_CP_NWD, If you check cptracker.com - you would see that it would be a bit early to expect a March interveiw - I believe these days it take about 50 to 70 days for the consulate to schedule an interview (assuming that your category is current).
You may also contact the consulate via email and ask them about the status of your case at
ivnd@state.gov
You may get the following reply:
===========================

Delhi. This is an automated response. Most information necessary to
