Hello Rohit, US these days has restricted jobs being offered to Nationals of other countries if the expertise is available in country. Hence to me it looks quite difficult for you to get job in US. However, there are agencies who are expert in channelising recruitments. You should approach them. But remember not to get fooled by touts.

Hi,
If you have completed M.Sc IT, applying to another MS degree will be very difficult. You can complete PGDCA or the first year of MS IT, this depends on the career outcome and the subjects taught. You have to tally accordingly, check if you want industry related course or want to go for research. You can also drop a few emails to the universities and find out their preference.

For B.Tech, you have to get a SAT score and apply for the individual universities not like India where in we appear for only one paper pan India. For more information, check the links below:
