Strictly speaking, mere bi-annual trips to the UK will not be sufficient to maintain your ILR status. You have to convince the IO that you intend to settle in the UK.

Are you applying for citizenship or for ancestry visa?

Under existing Immigration law there is still no charge (and no charging power) for transferring LTR /LTE stamps to new travel documents. The charging power will apply once the new immigration bill receives royal assent.

I think that they changed the procedure because of a legal problem- the candidate is the one who should apply for FLR not the employer.

Also my posting name somehow reverted to my login name.

Apart from that - an excellent job!
