H1B transfer and extension

[nithyaanandk]

Hi,
I have my current H1B valid through Jan 15th 2009 and I can file an extension for three more years. I now want to transfer my H1B to another company.

1) how much time does a regular H1B transfer takes?
2) When we file for a transfer does my H1B get extended for next 3 years?
3)If it doesn't get extended, when should I file for an extension? Can I file for an extension through my new company without getting the H1B transfer approval?

what should I do in this case?

Thanks,
Arun

1. 2-6 months
2. Depends on how much time the company requests in it's LCA.
3. You can get as many extensions till the 6 years are complete. I'm not sure I understand the second part of your question. Each H1b petition is independent.
