On January 27, President Trump signed an immigration ban, which sparks strong oppositions both in the United States and the international community. On the whole, the domestic oppositions mainly come from the Congress, the legal department, the executive branch and the state governments. Anbound Think Tank's chief researcher Chan Kung has pointed out in August last year and made a forward-looking forecast that the United States would transfer more power constraints to the Congress. Judging from Trump's personality, political advocacy and his core team values, the future he will push for more radical policies in the related areas. In this regard, these four oppositions other than the market will encircle Trump’s presidency for long-term, and will become forces that constraint Trump’s administration.
