There is just one solution..
1. Snatch Voting rights from these Illegal Migrants (Delhi, WB, Assam, Bihar and NE states)
2. Send them to refugee camp, refugee camp will be govern by Red Cross, Amnesty International and Muslim Ummah (if they want to)
3. Those migrants will live in refugee camp till there country accept them.
4. Don't allow them to have more than 1 kid, neuter them so that the count of refugee should not increase.
And finally
5. Send all to same refugee camp, who are protesting fro them. We don't want traitors, We dont want some one who destroy War memorials, We don't want some one who love there religion more than there nation... We don't want ingratitude animals..
Mission accomplished...
