The nation's immigration system "allows far too many unsafe, inadequately vetted people to access our country", Trump said, adding that the family-based method that brought the suspect to the United States is "incompatible with national security".
In a Monday statement issued in response to the attempted bombing at the Port Authority terminal subway station in NY, the President more specifically addressed the issue of chain migration. The proposal has not advanced in Congress.
Trump also touted his travel ban, which does not apply to the country from which the suspect immigrated. Mandhai immigrated to the USA on the basis of his parents' visa lottery win. Ullah entered the US on an immigrant visa in 2011 that he was able to obtain through a relative, a naturalized USA citizen who had won a visa through the lottery program, Tyler Houlton, a Department of Homeland Security spokesman said on Twitter. Ullah is a lawful permanent resident, or green card holder, spokesman Tyler Houlton said. My Executive action to restrict the entry of certain nationals from eight countries, which the Supreme Court recently allowed to take effect, is just one step forward in securing our immigration system.
White House press secretary Sarah Huckabee Sanders said Trump was "concerned that Congress, particularly Democrats, have failed to take action in some places where we feel we could have prevented this [attack]".
On December 8, U.S. Citizenship and Immigration Services (USCIS) Director Francis Cissna called for immigration reform that ends chain migration and the visa lottery in an op-ed.More news: Sen. Kirsten Gillibrand Says Trump Should Resign

But according to charging documents for Ullah, federal authorities traced the beginning of his radicalization to "at least approximately 2014" - three years after he came to the United States. After the attack, President Trump called on Congress and the Department of Justice to end the program.
President Trump has voiced support for the RAISE Act authored by senators Tom Cotton (R-AR) and David Perdue (R-GA). "The President is exactly correct about the changes we need to our immigration system". Family connections, including spouses, children and extended family, account for a large share of green cards given out each year.
That means Ullah was in the fourth (and most distant) family-relationship eligibility category - the minor child of a sibling of a US citizen over 21 years of age. Those families still must meet eligibility requirements to enter the United States and are screened and interviewed.
They push back on using the term chain migration, saying it tars a basic cornerstone of the current legal immigration structure: Allowing legal immigrants to bring their family members with them.
