What is free from immigration time restrictions ? I am indian and my wife also Indian, I have two sons elder one 9yrs and younger one 5yrs and my younger son born in uk. How much I need to pay when I apply and full family, can I put in one form or I need to use separate form . one more thing did I need to give my Life in the uk test cereficate when I apply naturalisaton because still I am waiting for my Life in the uk test cereficate after I get my ILR the Home Office did not return my cereficate.

Thank you
