Work in Mombassa

Volunteering is illegal in Kenya unless you have a work permit of sorts, or a 'Special Pass' (you would need support from the sponsoring organisation to obtain one for 3 months).

Unpaid work counts as work and is often seen as depriving a Kenyan of a job.  The other aspect which is often criticised is that volunteers show up, work for a few weeks, then disappear, so there is no continuity and local communities are left hanging.

I wouldn't recommend volunteering unofficially and 'under the radar'.  If caught you would very likely be arrested and deported.

For paid work you need a work permit and for that you need a job offer and ideally have expertise in an area where there is a skills shortage as employers must attempt to fill vacancies from the local labour market first.

Thanks for your reply. Not the response I hoped, but thanks
