tier 1 extension better by mail or premium service?

[szavelin]

1. It really doesn't matter to me, I am in no rush. Can I file extension application by mail? do I need to include my passport with it?

2. For a premium service, out of the locations listed, which one is the nearest to London??

Many thanks all

Sorry one more question, do I need to get biometrics done before applying, an where and how long does it take? I am really up against a short deadline here, mine ends on May 5th !

Thanks agian

PEO appointment before 5th may might be a bit out of reach

Croydon is the London Based PEO. You cannot do biometrics first if you are applying by post...And if you decide to do it in PEO biometrics is done on the same Day.

There are no appointments prior to the 5th. I don't mind sending it in by mail.

I understand that I don't need an attorney in general, but I don't have a mailing address in the UK, I don't know if it's true that my Tier 1 visa gets invalidated once I had entered on a tourist stamp, etc. Since I don't have the answers to these I might have to get a lawyer.
