I know this advice is given with the best intentions at heart, but based on my experience I would recommend a different approach.
Nowadays most employers do not accept paper applications or walk-in applications (unless maybe at restaurants or other hospitality jobs).
My advice to OP as a millennial who had to get a job in the US is to sign up for Indeed, ZipRecruiter, etc, and search for positions that you are interested in.
Job searches nowadays are all about volume, you are going to apply for literally anything remotely related to your field of expertise, and hope that one of them sticks.
Don't be surprised if send hundreds of applications and hear back from maybe a handful of them.
Make sure that every resume that you submit has keywords that are related to the position you are applying for since most companies use automatic filters to weed out applicants that are not relevant to the position. You want to make it past that first filter so an actual person can read your resume.
I would also suggest trying to make as many connections as possible. Join an amateur league at a sport that you enjoy, or find a local group of people devoted to one of your hobbies and start making connections.
If you have any other questions don't hesitate to let me know.
