The two Members of the Imperial Council started debating, it was a long one but can be summarized in one or two paragraphs. But before that, one must know what they are fighting here. 

The immigrants coming into Manchuria are mostly not undocumented and were able to get through easily as the Manchu-Hanese border is not yet as fortified as the regions that have been part of the Ruthenian Empire for the last ten years.  And since Manchuria was in the process of industrialization and urbanization, the Ruthenian Empire required a lot of workers to build infrastructures that made Manchuria the way it is now.

So the problem of immigration wasn't raised for the last five years until the Mayor of Manchuria started noticing an influx of immigrants flowing into his region from the Han Dynasty. And those people started demanding the same rights the Ruthenian Empire is providing to its citizens in the region.
