@Sachin,
Sorry to hear that bro. Let me tell you what happened with me.
Asylum filed: Jan 7, 2014
TPS filed: June 27, 2015
TPS case status: Fingerprint fee received
Asylum interview; Jan 20, 2016

Are you sure your interview was cancelled because you filed TPS? Did they tell you that? That could have been cancelled due to other reasons. On Friday Jan 8, I went to inquire about my status, and they told me that I have an interview on Jan 20. But, I never got any mail. I felt lucky to have inquired about my status that day. I submitted all my supporting documents on Jan 11 and I had an interview on Jan 20. I will have my decision on Feb 3. Let's see what they decide.

I don't think your asylum interview was re-scheduled because you had filed TPS. May be consider talking to an attorney bro. I had talked to few attorneys, and all of them said it was ok for me to file TPS while I had a pending asylum status. Some attorneys strongly advise you to file TPS, some say it doesn't really matter. I haven't heard any attorneys say NOT to file TPS unless I read the above comment from hari_nepali.

Good luck bro! Hope everything works out for you soon.
