hi there.
we are also in this prediciment. as far as im aware, you will not be allowed into the country unless you have a visa or someone who will sponsor you, your bf will be sponsored by his employer but he will n ot be able to sponsor you unless you are married.
it is possible for you to enter the country if you find a job b4 you go there as they will sponsor you.
i did think of doing this but to be honest there are too many grey areas.it is qatari law that single ppl of opposite sexes cannot live together, all it takes is one person to find out and tell the authorities and you and your partner could/probably would be deported.
my opinion is that"when in rome...", you should respect the countries laws and do it by the book, dont forget this is a country where ppl still have their hands chopped off for stealing, killed for rape etc..altough these are few and far between!
we are having a small civil wedding with just family for now and next year still planning our proper wedding.
hope this info helps a bit.
good luck
