A Desi will continue to stay in the United States of America due to the inertia of the Green Card until and unless an external force called Deportation is applied.
The force of deportation id defined by F = ma;
Where m = Amount Of Money Desi earned/saved in USA.
a = dm/dt, the rate at which Desi saved money.
(This is contrary to the common belief that Desi will return back after
making lot of money)
For each and every Desi that goes back to Desh for a temporary visit, a
Desi of the opposite sex will come to USA on a permanent visit.
