Maybe it's a good thing that your friend doesn't tell you how much it cost her :) For example, I never told my family that I spent almost $20,000 for this visa. Yes, the number is very high, but I think it's worth it to make my dream come true. I've been living in the United States for a year now and I don't regret spending that much money at all. You can calculate the
EB-3 Visa Cost for yourself by reading this article from eb3.work. It describes approximately how much money is spent on what and why such a huge amount is added up :) Maybe you can even estimate how much money your sister spent to get this visa.
