Driver's license.
Maybe it sounds obvious, but if you don't have a license, you are crippling yourself.
Even if you don't have a car, not having a license means you don't even have the option of renting one. Also, is is so "obvious" that if an employer notices that you don't have it, he will wonder why. Are you too stupid to drive? Crippled in some way? Economic problems? Have some criminal history? Alcoholic? You may have a legitimate reason, but it is still a red flag and you may need to clear yourself.
Second and just as obvious is a degree. Not so important if you have experience (though some large companies care), but a degree may be the key to a good first job that may launch the rest of your career.
I have never felt the need for any technical certification, not personally, the few I needed were paid by my employer for a specific mission, and done during work hours. Didn't get much use after that. Since I am not an English speaker, I probably could want something like a decent TOEIC score if I wanted to work in a large company in an English speaking country, but I am net even sure.
