I am uk citizen and my fiancee argentine. We are both in argentina and about to apply for the fiancee visa.

But i cannot find anywhere if we need to translate documets to english from spanish.

The documents i refer to and which are in spanish are:

birth certifcate..
Her work contract (as proof of her government job)
letter from her job confirming the last few years service. (as proof again)
her university grades
and finally, the first page of my tennancy agreement here which shows with the bills we pay, that we live together.

Please if someone could say if they are really nesaccary to translate.

Also, with the bith cert, does it need "apostille".

Thanks in advance
