Is elimination next week!!!

I think they should give this week as an introductory week and then only after next week's performance they shud start elimination round !! It will not be fair if anyone is eliminated with the first weeks dance !!
Its just my opinion !! Coz so many times some weeks they decide that there will be no elimination and push it to the next week
Anyways Good Luck to all the contestants !!!
Can we vote from USA??
