I'm a chartered accountant, and last month I got my employment visa.

Now I've found better opportunity with other company and  want to leave this organization due to some personal reason.

I have two query,
1.Whether labor ban will be imposed, if i leave this job before serving 6 months  (As i'm in to limited period contract and month probation period is there- what are the rights of employees to leave organization ) 
2. is there salary criteria for change of job
