Dear Suresh, if your bachelors degree says that it's a Btech - a 4 years US comparable degree, you may certainly apply to USA with GRE & TOEFL scores. The Ms in USA would be 1.5 to 2yrs & you may apply for the same one year prior to the intake you wish to go for. The intakes are majorly in Fall ie. sep of every year.

Dear Zeeshan, the actual conversion for the CGPA lies with the university & none would have the exact idea. Still you may self check it on the website for WES credential evaluation @ http://www.wes.org/students/igpacalc.asp.

There is no difference between MS and MTech as both are post graduation degree in Engineering. Indian universities award MTech and universities abroad award MS for post graduation in Engineering.
