To keep the opt period of 29 months as such

I have started my graduate education here in the u.s.a it will be very hard for the students who are coming from different countries to study. It opens us a wide platform and global exposure with multiple oppurtunuties for us to grow and make a name for us and for the company in which we may work. If the opt period is cut down to 12 months all these ambitions are a lost cause. So, please keep the opt period of 29 months and help us in makin the earth a better than it is now.
