does such a thing exist? i only have one passport i use for travel to/from doha and for tourism. it's actually easier to leave the country because they can see my working visa on the passport and they are sure that i actually have work and not some clueless victim of human trafficking sent to peddle drugs overseas (maybe that's what the immigration people think of everyone who go through them).

the only other kind of passport i know of are only those used by government officials for official travel. there's the seaman's passport but i think they're not really passports.
