How can I disagree with an such an esteem attorney as Mr. Bejar. He's 100% right. However, given that you will have made 3 entries in a period of 7 months (December with the RP, March and July) and have a very strong argument/reason that you do not and never intended to abandon your permanent resident status (e.g.: you were attending school abroad) I don't think you have to worry that there would be a finding that you abandoned your lpr status. Make sure you maintain and "renew" your ties to the U.S. such as having a current state drivers license, bank accounts (even if little $), Costco card, library card etc. Also, make sure you pay any fed or state taxes you are required to pay. Also, make sure you keep copies of your airline tickets, passport stamps, paperwork showing you lived in the U.S. from prior to leaving to the UK for studies etc. as a backup to prove your presence in the U.S. if that is ever questioned - maybe even years from now (in case your plans change and you live abroad again). Finally, to avoid any future problems, you should apply for naturalization as soon as you become eligible.
. I wouldn't leave the US in December (or in January) without having filed for another RP, received the biometrics appointment notification and went ahead to the ASC to request that I be taken that same day, given that I have to travel back to school.
It is not uncommon for ASCs to accept to take applicants at a much earlier date (that same day you appear there) when you can give them a good reason to do so. And yours is one heck of a good reason!
Do as I advise and you won't have to "beg" any consulate abroad and risk losing your US LPR status.
