Facts.
1. I have a job offer with a COS.
2. I have resigned from my current job before receiving my new Visa (I know stupid)

3. I have yet to apply for my Visa, my Job is supposed to start on the 10th March 2014, going to apply in person coming week.
4. I am currently on Tier 2 General since April 2013.
There is one big glicth this is what the new employer has mentioned in the COS.
Have you met the resident labour market test?:Y
Give details of the resident labour market test including where and when the post was advertised and reference number(s) for mandatory advertising:Exempt clause 28.8 UK Master's degree awarded - MSc in Advanced Computer Science from University of Leicester
On further inquiring the employer assures that they have done this before and this is the best way

Please please please advice

Thanks in advance.
