Visa quota for indian expat

Hello mates,
I have been selected as a senior executive in the company of sharhaj. I got offer letter in the month of july 2018, now its four months completed. But the HR is saying ur visa quota is in approval, last time he said quota has blocked and it can take one month or two, can not decide when we are going to receive. So i just want to know that work permit or sponsored entey permit takes much time like 4 months ans more?
Please review,
Thanks
Regards

It sounds like they have exceeded their employment quota and have applied to exceed / extend that.  It is a problem with your company and only they can tell you how long it will take - depends on many factors and can take a long long time to resolve.  Don't resign from your existing job.

When they gave offer letter to me they told me to be ready in 25 days, so i already left the job, waited for four months and just started new job last week.
Thanks..
