After marriage and before your current leave expires, apply under European law.

thank you so much for your prompt reply.
these links were very helpful,however i was unable to understand a few points....and these are as following...it would be very helpful if you could give me any answers to these..........

BIA wbsite says that in order to obtain residence card , eea citizen must have completed 12 months of job and then i can apply for residence card.until then passport will be stamped...
