Migrant smugglers were seen boasting how easy it is to illegally cross the border into America in a confronting clip showing a long line of men entering the U.S. smiling and waving at the camera.

The alarming footage, filmed on May 27 near Lukeville, Arizona, reveals a long line of migrant men casually climbing through a gap in the US-Mexico border wall and meeting no resistance or questioning. 

A caption in Spanish accompanying the video reads: 'Achieving their goals, the gents' followed by two prayer emojis. Text overlaid on the video also describes the crossing as a 'desert adventure.'

The remote outpost where the video was taken is around two and a half hours from Tucson, which has become the busiest point of illegal entry into the country, with 1,300 people a day crossing into the US in this area, according to federal statistics. 

It comes as a federal judge is set to rule on whether poverty would classify admission to the US on humanitarian grounds in a lawsuit filed by Texas and 20 other Republican leaning states against the Biden administration. 

Border Patrol agents told the New York Post they believe smugglers make these videos to promote the crossings to others. 

It is 'free information for everybody,' an unnamed agent told the Post. 

Migrants reportedly pay smugglers anywhere between $200 and $6,000 per person for assistance crossing the border. 

The issue of illegal migration at the border has become a hot political issue in recent months. 

Texas is currently challenging the Biden administration's program of allowing 30,000 people into the U.S. each month from Cuba, Haiti, Nicaragua and Venezuela combined on humanitarian grounds.
