L1, L2 Visa

Hi all, recently I had interview at Chennai on 16th November for L1B blanket, got 221g blue slip with not clearly approvable remark. I'm working with employer for 1 year 2 months & total experience is 7 years.

Need some advice, what could be the reasons & what are options available now?

This is how somewhat my interview went.

Me: I have developed a tool YYYY tool for the asset management companies, and started explaining the tool & I was about to tell the duties.. (I thought I'll explain the tool first & then tell what Im gonna do at client site)
She cuts me short here and says
VO: but what are you gonna do?

...................................

After this I dont remember if there was one more question or not, then next she kept typing in her computer

VO: I need to check something, please wait some time.
She went in somewhere & came back after some time (4-5 long mins) & gave me blue colored 221g slip, said application doesn't satisfy clauses for L1B & the exact reason are in section that is marked on this slip, give this to your HR department.
Me: ok, thank you.

Could it be salary amount?
And now
Can I apply for B1?
Can I apply for L1B individual under premium processing?
Please advise.

Thanks
