I live in Tijuana right now, I saw many Russia families with even babies and grandma, they need stay in Mexico for a month and there is a company who helps them with everything and they charge 2000$ per person after you enter America, 6 Russia families from my building entered America already, they used to be in Cancun for a month and then come to Tijuana for 3 days, I saw many successful cases myself, the K visa way May need wait years
