Tier 2 policy guidance states:
Given that I don't have an active CoS, does supplementary employment not come into play?202. You do not need to inform us of any supplementary employment, as long as it is:
• in the same profession and at the same professional level as the work for which your Certificate of Sponsorship was assigned; and
• no more than 20 hours per week; and
• outside of the normal working hours for which your Certificate of Sponsorship was assigned.
203. In addition, you must continue to work for your sponsor in the job recorded on your Certificate of Sponsorship.
Is there anything I can do at all until a decision is made? Can I volunteer and continue to study part-time (I'm on a course)?
204. You can also undertake voluntary work in any sector
187. You can study if you wish. There is no limit on the number of hours you can study or the type or level of course, provided this does not interfere with the job you have been sponsored to do. You can study anywhere you choose and you do not have to study with a sponsor registered under Tier 4 of the points-based system.
