1. No - he/she will just stamp your passport (the AV visa page) with a rectangular entry stamp showing date, Port of Entry and his/her number.
2. Maybe but IMHO unlikely - anectodal evidence on the board and personal experience from friends show that IO's are no longer routinely transfering visas from expired to valid passports at a POE. Requests for such are being met by the comment to apply for such a transfer through the Home Office after entry into the UK - general consensus is that this is in line with government policy to introduce a charge to transfer visas to a new passport as proscribed in the new immigration bill currently before the House of Lords. Ask the IO and see what happens - you may get lucky. The worst he/she can say is No. Tell us how you got on though
.
3. You are elgible to apply for Indefinite Leave To Remain in the UK after 4 years in the UK on an AV - you have wasted/lost a year. You need to apply for another AV or switch to another category leading to settlement to make up the 1 year - the only visa status complimenting the AV in terms of flexibility is the HSMP and even that is for a specific profession - you could do 'pot washing' on an AV and still get ILR.
Bon Voyage
