How do I get a position as a graduate research assistant?

<p>Hello guys,
I am an international student and I’m interested in going to GT for grad school. My area is aerospace engineering. How do I get a position as a graduate research assistant (GRA)? Is there a separate application process? I know it depends mostly on each department’s criteria, but how does the GRA selection work?
Thanks!</p>

<p>Hi
I am also international student in GT majoring in AE. GPA+professor recommendation is the key point</p>
