There are the three ways to win the Green Card Lottery: (1) enter;  (2)  enter;  and (3)  enter again (not all in the same year, of course).  Assuming you have followed all the rules, winning the Green Card Lottery depends only on luck.  Do not expect to win, but have faith and keep trying.  Each year is another chance.  Many people win on their second, third, forth or fifth attempt.  Enter every year and, while you’re at it, make sure your husband or wife is also entered because if your spouse wins, you win too.   Encourage your relatives, your mother, father, sisters, brothers, and children over 18 to enter also because, if one of them wins, he or she might be able to sponsor you for a Green Card in the future under another program.
