am a US citizen and would like to bring my parents and my 17 years old brother. I just want to know what is the proper and fastest way to bring them.

I assume that you are over the age of 21. The best way to have your parents and your 17-year-old brother over is to first sponsor your parents, and once they are here, they should immediately sponsor your brother. If all goes well, everyone should be here within 2-3 years.
