Conclusion
Millions of people apply and about 40% are invalidated at the beginning because of small errors. Follow all instructions exactly.
Make sure you are eligible. You must have either education or work history. If you do not, don’t apply. You will just lose your application fee.
Once you decide to apply for a DV, start gathering all the information you will need. It will take time to get it certified, copied, translated, and sometimes, even located. Check regularly to see if you have received an invitation and then respond immediately.
And most of all, be accurate and thorough. Good luck!
