Wrong Date of Birth

[arash_uk]

Hi,

one of my friend is facing a big issue for her husband's spouse visa application.

She became a UK citizen over 35 years ago and as she immigrated from a non-Christian country, the date of birth on her non-UK passport was not in Georgian calendar. Thus, when they converted it they made a mistake at the time by just couple of days (for example 16 April 1950 instead of 20 April 1950)

Throughout these years she has not noticed it until now that she wants to bring her husband here and she suddenly found out about the issue. the problem is that some of their supporting documents are from her first country and so the date of births are correct.

what could she do? I've look the internet but could not find anything relevant. Is a couple of days mistake a big issue?

Thank you for your help in advance.
