My brother intended to attend a convention in Germany and submitted his visa application.
He was asked to bring a sponsor/guarantor, and as I didn't have money in my account, I could not help the guy.

After two weeks of being downcast, he begged me to help him to at least go and retrieve his passport from the embassy, that they had even declined all his frineds that applied for the same convention. I got there and they told me they asked my brother to bring some documents which he did not, that I should go and get the documents before they release his passport.
I went around begging everybody I know to sponsor him, and finally, a big sister agreed.

I got there again, they said Travel Insurance date versus flight date, I had to run helter-skelter again.

I have been asked to return tomorrow with the Insurance documents, that they will process and print tomorrow. They started forming that they will treat it as urgent because the travel date is supposed to be March 11th.

My question is, will they issue him a visa after all this suffer I have suffered like this? Also, his sponsor had only N650k in her account, can that suffice to sponsor him?

I will appreciate your responses

There's a probabilty they give him I trust they might just want to see some kind of committment from him
