do US recuiters actually discard applications from abroad as fraud?

i'm a us citizen who has spent more than half of their life outside the us, and i'm trying to go back (ideally with a job lined up). i've spent time applying to jobs in the us, always specifying that i'm ready to immediately relocate.

is it true that my applications might not even be so much as opened? 😭 if so, how can i work around this issue? i know jobs are in general limited, but there are so many opportunities in the us for what i want to do as opposed to where i am now
