Thank you ammeck09 for your responce.
My aunt is having her interview in Zimbabwe, and the embassy requested for birth/marriage/police/highschool/photos-----both original and copies for principal applicant and dependants. They did not ask for the affidavit but i know if she does not have her own bank statements to show then she'll need the affidavit right?
Also, she has 2 dependants,when she applied one of them was 20years old but turned 21 after she had already submitted the DS-230, now when she received the 2nd NL there were only 2 names hers and that of the 17 year old dependant, the now 21 year old was not included. A fter contacting KCC to find out why he was not included she was told that because he is now 21 that is why they did not include him.She explained to them that their own LAW states that if the dependant was less than 21 years at the time of the application and turns 21 before the interview then the LAW prevents them from ageing out and will be treated and considered as if they were still under 21 years depending on the circumstance. KCC then told her thats yes she was right and they are aware of that and she MUSTstill go with him to the interview as it will be up to the CO do determine whether to grant him visa or not.
Now i dont think it will be a problem for the CO to grant him a visa as in his case it just happens that he is fully dependant on the mother because he had meningitis when he was a child and that led to him being a bit slow in learning.He is not on any medication at all but when you see him you can tell that he is not your typical 21 year old, and can not live on his own so he definately needs the mother. But now the problem is if you say the interview letter is the same as the 2nd NL then how will they let him inside the embassy when his name is not on that letter?
