The situation with underfunding of the Ministry of Interior is not easy, we agree. What else can you suggest?
A visa regime with the countries of Central Asia and Transcaucasia, at the same time as the transition to a full organizational set-up, will reduce the burden on the Ministry of the Interior.
Also, intergovernmental agreements can be made with countries that provide for immigrants according to which they will pay all deportation costs themselves. They will agree, because they have nowhere to go.
It is also possible to increase the taxes on the use of foreign labor so that both the employer and the immigrant pay more.
It is also possible to identify the adaptation and integration costs of the immigrants as useless and direct them to workers' wages. Prohibit state funding for various national and cultural diasporas and autonomies. You give salaries to cops, not pilaf festivals!
What else can you suggest? Let's think, give me a hint.
