Письменно ответить на вопросы. 1. When was a number of measures taken to limit immigration?

Скорее всего, речь идет об ограничении иммиграции в США (так как предмет - английский язык), поэтому будем рассатривать именно эту страну.

The immigration reduction movement is common for some countries. This trend began at the beginning of XX century. One of the first actions done by the US government was an \"Immigration act of 1924\". This act limited the number of immigrants allowed to entry into the US.

More severe attempts to limit immigration were conducted by Donald Trump. He has restricted the rights of immigrants and refugees, built a US-Mexico border wall (2000 meters) and currently he tries to stop birth tourism by the law tightening.
