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!!
