how much money i can send to india when i am pursuing my masters

hello guyz !

this is prashanth pursuing my masters in usa

actually i have friend suffering with health problems in "india "and i wanna transfer money to her after collecting funds here

is this possible?

will i face any visa or immigration problems in future if i send money to my friend?

It should be possible. Depending on the service you use to send money, they will ask you to share your employment details, govt issued photo id, etc. There would be some limits, I suggest you email or call the service providers like Xoom, Remit2India, etc. to get some idea on the restrictions or policies.
