How many times H1B visa can be extended before going to US?

[ramu.chekuri]

I got my H1B visa approved for one year till 30th September 2016.

I have applied for H1B in 2015 January.

I cannot go to US due to personal reasons till December 2016 and also
I want to apply for an extension in 2017 only.

Please let me know if it is possible to apply for extension in 2017.

Can I extend my visa several times in this way if my employer is willing to do it?

Do I need to go through lottery process again for extension?

Please help me out.

Thanks so much in advance.

H1B CAP is valid for 6 years. Until you utilize all 6 years in your H1B CAP, your employer (or even a new employer) can keep filing CAP exempt H1B petitions for you. No need to go through quota again.
