There were many discussions about how early one can send the application - on the 1st of October, or when the number becomes current. How about the opposite question: what is the latest possible date to send the documents? In theory it is the last day of September, '09, I know But I am more interested in practice. I am still expecting some paperwork from my home country, and the number becomes current this coming October. How long can I wait, and what are the cons?
