good day neel,
just so you know, there are also lots of indians here in our country too and speaks english (even tagalog) clearly. although to some extent, their accent is far different from american, still, we are able to understand them simply because they speak a straight-forward english (i.e. no slang or idioms, just a literal english). I believe that in any case, being simple and straight is the most important thing in communicating with others using other / foreign language.
:)
