My employer(semi Goverment Organization) told me that they have been unable to obtain an Visa for me, they didn't told me any reason yet. I gave them clean documents and my background is also clearn back here in India.
And now they have withdraw my offer also :(.. this thing really tested my patience for 3 month now.

Is there any Quota system for visa linked to each country for every year, or quota for each Employer per year ? (may be the quota is expired during my application)

Can anyone tell me what could be the plausible reason which they might aware of or come across your mind.
