k1 Visa joined First and Middle name as One

[gedaa86 5]

Hi,

My fiance received his k1 visa a couple of months back. In all of the applications and paper work that we filled , his name was as the following for example:

First: A

Middle: B

Last: C

But his passport has an additional name between the middle and last as all arabic names have that: E

But we were surprised when the social security office worker told us that the visa joined the first and middle name together and made them as the first name : A B

the middle as : E

and last as C

What can I do to correct his and who do I contact to fix this?

Thanks
