im a indian a american indian sending false information to my friends and even to indian local police can i file defamation suit against him?

With respect to whether you--a citizen of India--have the right to file suit against a Virginia resident, the answer is yes.  The larger issue is whether you have a viable defamation action.  That is going to depend on a number of factors, the key elements of which are laid out here.  You should consult a lawyer to determine whether the false statements amount to actionable defamation.  If so, you can bring suit in the jurisdiction where the defendant resides.
