Hello,
I heard there are people who got their 2 petitions selected in lottery in 2015. But i did not see anywhere that happened in 2016 where someone applied 2 petitions and got both selected. I heard that USCIS is filtering petitions based on name, DOB, etc… before taking them to the lottery stage, though there was no official announcement on that by USCIS. Is it true? If so applying multiple petitions would be waste of money, time.
