On an Entry-Level Job (not a legal assistant)
Don't let your major(s) hold you back. Apply any and everywhere you're interested in (unless the position calls or a specific major obvs) and see what happens. I would totally echo bretby's comment above, but I would also consider the options below too.
On Being a Legal Assistant
I disagree with oidsedidy. Do not become a paralegal, thinking it will help you in law school: 1) if you're only working for 1 year, you're not going to be fully exposed to thaaaaat much since the first 3-6 months will be training (of course this depends on where you work) 2) if you become a corporate paralegal, none of oidsedidy's comments really apply and 3) you'll risk going into law school with a false confidence that you're going to beat everyone else and be the top of your class--and this might actually hinder your performance.
I'm speaking from experience. I was a paralegal for a few years and I just completed 1L. There's hardly any correlation between killing doctrinal classes or doing well in law school and being a legal assistant. The skills that you need to do well in law school (i.e. be able to regurgitate black letter law while analyzing a fact pattern as quickly as possible) are not really related to those skills that you pick up as a paralegal. Sure, being familiar with the UCC in contracts or knowing what a deposition is in civil procedure will be beneficial, but it's not a huge leg-up. Doing well in law school basically boils down to being diligent and being able to write a law exam well. There are a bunch of threads on this site, that tell you how to do that.
Being a paralegal gives you a small boost when it comes to applying to law schools, but the real benefit of being a paralegal kicks in when you're applying to jobs for your 1L summer or your 2L summer. Being able to say I want to do x practice area because I worked in it yada yada is great. Forming connections with attorney mentors is also really valuable in terms of getting advice for which practice areas suit you, which firms to consider and obviously getting hired. This is why you should consider applying for a few legal assistant positions. And if there aren't any in your town in Wyoming, don't be afraid to move. Take this opportunity to live and explore a new city. Which brings me to my next point...
If you're going to become a waitress or bartend or teach or anything of that nature, do it abroad. You have so much more to gain by holding a position like this abroad than you would if you just stayed home. There are also a plethora of non-profit legal organizations that are just like or similar to the Innocence Project that you can volunteer with abroad. You'll learn a lot about yourself, you'll meet new people and you'll gain have new experiences. You can also work on picking up (or honing your skills) in a foreign language (this can be helpful for employment too). I can keep going, but I have to get back to work. Feel free to PM me if you have any questions!
