I just have one reservation on what you have written up there. As far as I know, the new regulations do not give you 60 days option twice. You will have one 60 day option to prepare for departure after your OPT ends provided your OPT starts right after your graduation. If this is true, do not think smart and start your OPT after 2 months of graduation. It will not extend the number of days you can stay in USA. If you start your OPT after 2 months of graduation, you will have to leave the country right after your OPT ends, provided you have no other valid visa. PS: I am not 100% certain about whatever I have written but I heard about it. So, confirm this before taking this as a legal statement.
