The chances of winning a Green Card vary from year to year due to the number of participants and the legal requirements. Each world region receives a certain number of Green Cards. The average chance of winning a Green Card with The American Dream is about 1:25 to 1:75, depending on the region and year (for Europeans recently around 1:45).
Due to the new passport regulations there will be significantly fewer participants as of 2019, so the chances will probably rise again to 1:25! That means almost every 25th applicant actually receives a Green Card. Statistically, the chances of winning a Green Card are higher than the odds of winning money in the lottery!
It is important to beware of the fact that the Green Card Lottery only takes place once a year. That is why it is vital to take advantage of this chance when you have it! Married couples can each submit their own separate applications and double their chances of winning.
