I have to do Ms in the USA tell me about application process and other things
Process is quite simple but costly. If you don't have any budget problem then it's fine.
First you will have to appear in the GRE, IELTS and Toefl. I know most of the colleges in US only demands GRE score but why to take risk. Or you can simply appear GRE only.
Get a good score of above 320+, apply for the college's you have shorlishort, keep one or two solid LOR's and SOP. Maintain a good CGPA in your graduation with varovar extra curricular activities also.
All the best!!
