Tighter Immigration Rules Put East Africa’s Cross-Border Movement Under Pressure
Tanzania has detained 134 Burundian nationals in the Mara region for allegedly entering or staying in the country without meeting immigration requirements, as authorities step up checks on migrants.

The arrests come amid a wider tightening of immigration enforcement in East Africa. Tanzania’s latest operation is expected to continue, raising concerns for people who regularly move across the region for work, trade and other economic activities.
In neighbouring Kenya, authorities have also increased scrutiny of foreign traders, particularly those operating small businesses without the required permits. The government has given affected traders 90 days to regularise their documents, following concerns raised by Burundi and other regional stakeholders over the treatment of foreign nationals.
The developments highlight the growing tension between immigration control and the movement of people across East African borders. For migrants and small-scale traders who depend on cross-border activity for their livelihoods, stricter enforcement could mean greater difficulty accessing markets and earning a living.
With Tanzania and Kenya both tightening immigration checks, the issue is becoming part of a wider debate over how East African countries can enforce their immigration laws while protecting migrant rights and maintaining the region’s long-standing push for easier movement across borders.
