What concern(s) is the document articulating regarding immigration?

To fully answer your question, I would require more specific and contextual information about the document you are referring to. However, I can outline some common concerns often articulated regarding immigration:

1. Economic impact: The document may discuss concerns about the possible economic effects of immigration, such as the impact on job availability, wages, welfare expenditure, or contributions to the economy.

2. National security and public safety: It might express concerns about ensuring border control and preventing threats posed by potential terrorists or criminals entering the country.

3. Cultural and social impact: The document may articulate concerns about the preservation of national identity or traditions, potential language barriers, social integration, or assimilation of immigrants.

4. Legal and political considerations: It might raise concerns related to the enforcement of immigration laws, issues with legal processes, policy effectiveness, or the political implications of immigration policies.

5. Humanitarian and human rights aspects: The document may discuss concerns related to refugee and asylum-seeker protection, treatment of immigrants, family separations, detention conditions, or violations of human rights.

6. Economic and demographic opportunities: It might articulate concerns regarding workforce shortages, labor market needs, demographic shifts, or the potential contributions of immigrants to an aging population.

Again, without a specific document reference, it is difficult to provide a precise analysis of the concerns discussed.
