The place where I am living now been visited by immigration officer in 2016 July 30 to arrest different people while I was also questioned by immigration officer about how long i was with my ex wife,how long we are being separated , why i am not divorced yet, how long have i been living in current address and so on. I couldn't give them correct answer as i couldn't remember the date, instead they rang my ex and got answer from her which was different than what i have answered them. After they were saying me that i was lied to them, probably we got married for paper and all that rubbish stuffs which is absolutely not!! Although i was trying be honest with them but they took my passport away and told me that HO might revoke my Residence Card therefore i should look for immigration advisor

-Lived together after married for 2years and 1 month 11days
-Residence card valid until 26 june 2017
- Sill not divorced
-living separately
-Passport Taken Away 30 July 2016 from current address
Questions are
1)what should I do now shall I just call HO and ask my passport back or wait for another couples of months ? Its been 3 months haven't heard nothing from them. I don't think they will just return my passport if they won't what shall i do?
2) I am thinking to wait till 21 jan 2017 and will do divorce process means i will be still married with her for 5 years.Does it make any difference even if i process now ??
3) After if am divorced what application should i apply for Permanent Residence (PR) or Retained Rights of Residence (ROR)?
Please give me some advice that would be really appreciated !! many Thanks
