Final answer:
The correct statement is that immigration benefits have become more difficult to access. The Trump Administration had a more restrictive approach to immigration, while President Biden has been more positive about it.
Step-by-step explanation:
The correct statement about the changes made by the U.S. government in the past year regarding immigration restrictions is that immigration benefits have become more difficult to access.
The Trump Administration had a more restrictive approach to immigration, including plans for a border wall and increased deportation of undocumented immigrants. On the other hand, President Biden has been more positive about immigration.
Given the presence of considerable disagreement within the overall population about the desirability of immigration, it is unlikely that any significant immigration reform will take place in the near future.
