I’m considering 35P as my MOS, are there a lot of civilian opportunities corresponding to the skills you acquire in this MOS?

Once you make it to the rank of specialist, you can also join civil Affairs and use your language to your advantage. Civil affairs is considered special operations and you have to be a specialist promotable to Sergeant or a senior first lieutenant who is completed his Captain's career course. Something to think about.

Coming from a 35P with 9 years TIS as 35P, my first assignment was working for NSA. Most of the civilians at NSA are veterans from one of the branches (though, you will need a 4-year degree to get that sweet CIV gig). I recently updated my profile on clearancejobs.com (since you will need a TS in order to be a 35P), and within days I was getting offers for contracting jobs ranging from $85K to $125K. So the opportunities are out there. I know many 35P soldiers who quit after their first enlistment and now out-earn me several times over.

There are a number of 35 series MOSs other than 35P that fit in well with the federal government if that is your end goal. Some fit in very well while others do not, for example 35L has a mission in the states whereas 35M does not. However, being a 35M would enable you to gain a language and another skill.
