Nine migrants from four African countries arrived in Cameroon on Wednesday after being expelled by the United States under a bilateral arrangement.
Six women and three men came from Ghana, Angola, Ethiopia, and Congo-Brazzaville, their lawyer told AFP on Thursday.
Cameroon is participating in a controversial US scheme, with this the third flight since January, lawyers said.
According to The New York Times, Washington is paying Cameroon 30 million dollars to participate in the relocation programme.
Similar agreements exist with Equatorial Guinea, Ghana, Rwanda, South Sudan, Eswatini, and the Democratic Republic of Congo.
Most migrants cannot be deported to their home countries due to US court rulings citing safety concerns.
Of seventeen previously deported to Cameroon, four were later sent onward to Morocco, Angola, and Senegal.
Two Moroccan women had their fears for safety recognised by US courts, yet now live in hiding after return.
Thirteen others remain in a Cameroon-run centre with IOM support and may apply for asylum if they choose.
Human Rights Watch criticised the opaque agreements in September, saying the expulsions violate international law and should be rejected.
