Looking at this thread (eea-route-applications/retaining-eea-family-member-right-of-residence-t161604.html) and majamcr's valuable input I think my route suppose to be:
1. 2012 December - Marriage
2. 2013 February - I have obtained the EEA2 family permit valid till 2018 Feb
3. 2014 August - My spouse will apply for her PR/ILR through EEA3
4. 2017 December - Apply for PR/ILR through EEA4
5. Finally the BC (1 year after getting the PR/ILR)
However It will be helpful, if one of you experts can drop some wisdom please?
Thank you all.
