Hi, My uncle has made an application for a visitor visa. I have sent all the required documents but missed to provide them my passport copy as it is a vital document. Is it possible to contact the embassy and provide them the missing info or please advise me what I should do to avoid to the outcome....

I am certain, that your documents and everything looks fine. I can feel you, cos I have been into this rollercoaster couple of months ago .

You should be fine! all the best, let us know the outcome.
