(CNN) It has recently been found that more than one million immigrants have been arrested for illegally crossing the border from Mexico to the United States since October last year. Two Homeland Security officials have revealed. The situation has already exceeded the level at the time of the crisis of immigration inundation that occurred around the border with Mexico in 2019. The Biden administration has been struggling to deal with the large number of arrests on the Mexican border since the beginning of this year. Homeland Security Secretary Mallorcus expressed a sense of crisis in March this year that he was on the verge of facing more illegal cross-borders than in the last two decades. The US Customs and Border Protection has not yet announced the number of arrests in June this year. However, he acknowledged that the number of people has already exceeded 1 million within the 2021 fiscal year until September 30th this year. Many of the arrested have tried to cross the border many times. The impact of measures against the new coronavirus has also been pointed out. Last year, the Biden administration introduced a policy of promptly sending back arrests near the border. However, unaccompanied children are not eligible. According to officials, when looking at the average figures for 21 days, the number of cross-border acts caught in June this year reached more than 6,300 people every day.
