How to get a FULLBRIGHT Scholarship?

[Haroon1]

Dear Torsten,
Thank you very much for your mails. I have no words to thank you.
I am working as a Lecturer of Earth Sciences in University of Sargodha, Pakistan.
It is located in a remote area in Pakistan.
Before that I done M.Sc. in Petroleum Geology and Geotectonics(specialization in Geology) from University of the Punjab, Lahore.
I want to get a master degree and a Phd from some American University.
For this I am preparing International GRE and TOEFL. I have not started working on TOEFL yet. As my focus for the time is on GRE. After doing GRE I will do TOEFL. Is this strategy good?
As I have time till the next May 2011.
I want to apply for FULLBRIGHT Scholarship.
If you have any information about how much score of GRE and TOEFL is required for this Scholarship(in my discipline)?
Your emails are a great fuel for me for understanding the English Language.
I need your special attention. As I want to move to international Oil industry and market.
Best Regards,
Syed Haroon Ali
