For example, from the dvlottery website :
DV-2018 Entrants may enter their confirmation information through the link below starting at noon (EDT) on May 2, 2017. The DV-2018 registration period opens on October 4, 2016, and closes on November 7, 2016. DV-2018 Entrants should keep their confirmation number until at least September 30, 2018.
Are the results available on May 2, 2017 the same as on September 30, 2018, or they are released by quota?
In other words, if I check my number on May 2, 2017 and I find that I've not been selected, is there a chance that I will be selected before September 30, 2018 or it is a definitive result?
Thanks in advance, and if the official website mentions something about this please attach it.
