Days after the Supreme Court of the United States upheld birthright citizenship in the country, the Trump administration continues to tackle the rise of birth tourism.The US Supreme Court rejected a central plank of President Donald Trump's immigration agenda on Tuesday, deeming his plan to restrict birthright citizenship to be unconstitutional. (Bloomberg/Representational)As per local reports, the Justice Department directed prosecutors to look into alleged cases of birth tourism, especially the ones which are suspected to be fraudulent.“The Department of Justice will zealously protect the sanctity of United States citizenship by investigating and prosecuting those who fraudulently exploit our immigration system,” Colin McDonald, head of the Justice Department’s fraud division, wrote in the memo, as reported by The Hill.According to Reuters, the DOJ memo further added that prosecutors should look into individuals who enter the US "under false pretences” to give birth and obtain citizenship for their child.This memo follows SCOTUS's ruling against Trump's executive order to end birthright citizenship and upholding the clause governed by the 14th Amendment of the US Constitution.Also Read | From Jus Soli to Wong Kim Ark: The trials and turns of birthright citizenship in USIn addition, the Justice Department memo comes months after the Department of Homeland Security launched a "birth tourism initiative" that directed investigations into the practice.What is birth tourism?Birth Tourism is the practice of travelling to another country for the main purpose of giving birth there.
