What department can I find to solve the problem of landless after immigration?

Can be reflected to the local government.

1, contract disputes can be complained to the township people's government, and the township people's government can mediate.

2. If mediation fails, you may apply to the Rural Land Contract Arbitration Committee of the county-level agricultural department for arbitration or bring a lawsuit to the people's court.

3. Those involved in indiscriminate occupation of cultivated land may complain to the land management department at a higher level.

4. You can consult or report to the Bureau of Land and Resources.
