i had tried to do survey many times but rejected everytime....can i do it from india?or have my country problem for survey..?plz inform me.....

Yes. If there is a survey for you, you can do it.
If there isn't, you cant.

Yes you can, i am from India too and only recently i am able to do 2-3 surveys daily. The key is to stay truthful and read all the information and questions very carefully. If they find out you are a straight liner or just rush with your answers, you may get disqualified.
Check for surveys on Yoursurveys and Opinionworld routers in the survey page, they are your best shot at completing.
