In a speech delivered at the Republican National Convention, Texas Governor Greg Abbott reiterated his commitment to busing migrants from border cities to Chicago. This controversial practice, aimed at protesting federal policies on immigration, has already seen the transportation of nearly 45,000 migrants and 950 buses to the Democrat-led city, according to the latest data.

Addressing the RNC crowd, Governor Abbott declared that the migrant buses will continue to roll until the border is secured, while the audience chanted "send them back." Pointing fingers at President Joe Biden and Democratic-led sanctuary cities, Abbott stated, "I took the border to them."

The majority of migrants arriving in Chicago on these buses are from Venezuela, a country grappling with political upheaval, economic crisis, food and medicine shortages, surging inflation, rising unemployment, and violent crime. Upon arrival, most Venezuelans are granted a parole period of 60 days or less, which allows them temporary permission to be in the United States and apply for work permits.

However, many migrants have struggled to support themselves as only a few have been granted additional eligibility for work permits. This has resulted in difficulties for them in finding adequate bilingual schooling for their children and settling in neighborhoods with limited resources.

The influx of migrants has put a strain on Chicago, prompting the city to hastily open dozens of temporary shelters as migrants were forced to sleep on police station floors. Some shelters have faced community opposition, and there have been reports of unsanitary conditions, including the tragic case of a 5-year-old boy who died from sepsis in a Pilsen shelter.

In response to the crisis, President Biden signed executive orders last month temporarily closing the southern U.S. border, marking the most restrictive border policy implemented by a modern Democratic president. Since then, border crossings have significantly declined.

While the busing of migrants has slowed since the beginning of the year, Governor Abbott has been known to escalate tensions as the national spotlight turns to Chicago for the upcoming Democratic National Convention. A top aide to Mayor Brandon Johnson previously stated that up to 10 buses a day could arrive as Republican governors attempt to embarrass Democratic mayors closer to the convention.

Despite concerns, Democratic delegates have maintained that the migrant crisis will not distract or impact the convention. Efforts to accommodate the influx of migrants include the opening of a new shelter at a former convent and school building in Portage Park, which the city has leased for free. The state is also funding two additional shelters on the South Side after Governor JB Pritzker intervened to prevent a massive tent shelter at an environmentally contaminated location in Brighton Park.

Currently, there are 17 active migrant shelters in the city, and the Johnson administration has implemented a 60-day stay limit amid pushback from officials and volunteers who consider the policy inhumane. Around 1,500 individuals have exited the shelters due to the policy, with more than 900 returning to a "landing zone" for additional shelter, according to city data.

Efforts are underway to place migrants into their own housing with three months of rental assistance, although this program has faced criticism for providing insufficient stability and rushing migrants into unlivable apartments.

Mayor Brandon Johnson has repeatedly called on the Biden administration to provide more resources for migrant assistance and to facilitate the process of obtaining work permits. The city has pledged to integrate its migrant and homelessness shelters into a unified system once the crisis abates, aiming to create a stronger support network for vulnerable Chicagoans.

Governor Abbott's decision to transport migrants to Chicago continues to draw condemnation from Mayor Johnson, who accuses him of creating chaos and showing disregard for migrant families. The mayor has referred to the practice as "wicked" and has consistently urged the Biden administration to address the situation.

As the migrant crisis persists, Chicago grapples with the challenges of accommodating and supporting the increasing number of arrivals, while seeking long-term solutions to ensure the well-being of both the migrants and the local community.
