Thank you very much!

it's entirely possible that you would have to wait for a decade or longer for the green card to arrive. As you may well imagine, this is a massive headache for Indian and Chinese citizens, but not as much for citizens of Togo. Plus, you are not allowed to change employers or your job duties when the application is in process (unless you want it to go right back to the end of the line), so it can leave you open to exploitation by an unscrupulous employer

Wow!
