I understand from the tier 2 sponsorship guidance that one cannot take more than 4 weeks of unpaid leave in the UK. Hence, this makes me wonder if it is actually possible to take up a 6 months of career break while on a Tier 2 visa? Has anyone done this before or is this not plausible at all? I would be grateful if anyone who has taken an unpaid career break for 6 months to share how they structured their break

On a side note, would it be possible to terminate my visa and reapply for one in a years time so I can take my career break? I understand there is a 12 months cooling off period. Would this work?
Thanks for your help in advance!
