No don't do it. French foreign legion sounds cool, sounds like a unique way to shape your life, make you stand out. Overall it'll be harsh, no one will give you the respect you feel like you deserve, your pay will be **** and France will send you into battle as cannon fodder. I get it, its infantry, but being Russian or FFL is so much worse. Russias still in a cold war state of mind, constantly trying to recover lost lands, after all they were recently in war with a 1st world country (Ukraine), even though they disguised their soldiers as rebels. Russian government would definitely utilize their infantry and unless you want to be put in a position where you have to go against the interest of the US government, which usually doesn't work out, then i'd avoid that. You can easily find work in the US you just have to literally apply for everything, find a shitty job, and keep applying for everything.
