I know that there is an assumption that a certain number of people who win will change their minds and not want to go, so there are more applicants who win than there are visas available. It is certainly conceivable that if the total available visas is hit while you havenu2019t yet filled the form, you will not be included.In addition, some people delay for so long that they donu2019t meet the deadline, or the system is so busy with last-minute applicants that they canu2019t finish the form on time, but thatu2019s a different issue.It is always a good idea to do the form as soon as possible, just to be sure itu2019s accepted and is valid. If any part of my answer is incorrect and someone dealing with the DV from the processing end knows, I hope theyu2019ll correct me.
