it is mentioned visa validity:17/11/2013
date of issue is 21/05/2013. so it means 6 months, but some bodys are telling before 3 months we have to enter, after the date of issue. and visas are valid only 3 months.
still im getting doubt it will be valid to enter untill 17/11/2013 or before that we have to enter and shall be done all formalities like medicle etc....etc...
