Thanks somv for reply. I ask to one MA he is Australian he told me that 3 years ban applies on you if i am seeking any temporary visa (student,tourists) etc. but if I apply for any PR visa it does not apply one me. But i am seeking for second opinion. And section 48 applies on me if i am IN Australia. But I already left Australia. And applied for 186 as a secondary applicant from my home country. I am honest with the immigration and i declared everything in the form. But that MA told me that they always looks for big crimanal conduction which i dont have any. But i know they will check my immigration history when they will decide my visa. If anyone can help who is got same situation or knows abt it. That will be greatful. Thanks in advanced.
