To Whom it May Concern,

Please allow me to give a short introduction of me and my situation:
My name is XX XX and my family and I were always interested in living in the United States therefore we participated in the lottery.

Thankfully, we won the Green Card XX, so therefore we were invited to an interview at the American Embassy in Warsaw.

Unfortunately, I went to the interview on my own, because of a family problem they could not accompany myself to the interview on XX.XX.XXXX.

The result of this is, that they didn't get the VISA. 

Now, I’m in the U.S. and waiting for my Green Card to be issued.

 
Finally, my VISA expires on August XX, XXXX, but my family ( wife XX XX, and my son XX XX) still haven’t the possibility to get to the consulate to open the VISA.
The main point is that, I am concerned about my family, who are still in Ukraine.

I am kindly requesting that you suggest what I should do to bring my family to the United States.

Yours Sincerely,
XX XX
