The book provides a comparative assessment of the legal regimes governing movement of persons in East African region. It compares the approaches used by the regional integration arrangements adopted both at the continental and sub-regional level in governing mobility matters. In doing so, it assesses the policy coherence in the RECs and evaluates the strengths and weaknesses as well as the implementation impediments. The book provides a detailed assessment of what and who is covered in multilateral regimes governing, directly and indirectly, mobilities; and identifies lesson that can be drawn from regional integration arrangements in other parts of the world- particularly the EU. The book also offers analysis of the different challenges hampering implementation of the mobility regimes adopted in the selected African RECs and proposes potential policy and legal recommendation. The book can be used by policy makers and researchers working on African integrations matters.
