The bus terminal in Brownsville, Texas is a place that humanity should avoid.

Here, human fate is forced together among worn benches in polished wood and exposed plastic chairs for migrants to rest tired backs on.

Most of them come this day are from Honduras and Guatemala.

Common to most of the people we meet is that they have heard that "Mr Biden" will help them.

The message comes from friends, relatives, other migrants and carelessly interpreted news bulletins.

The border between the United States and Mexico is closed, but there are now important exceptions, which allow migrants to enter the country.

And children are the key to the United States.

Promises evoke hope

Already during the election campaign, Joe Biden signaled major and extensive changes in American migration policy.

The most groundbreaking reforms would lead to those who came to the United States illegally as children being offered the opportunity to obtain citizenship.

The same was true of the undocumented adults.

However, the requirements would be many.

But these proposals are far from reality.

Decisions must be made by Congress and it is highly uncertain whether they will pass.

The changes that have already taken place, however, are that wall construction has been stopped along the southern border of the United States and that children can no longer be brought back to Mexico without a proper asylum investigation.

This also gives parents who come alone with their child an opportunity to stay in the United States during the asylum investigation.

The hopes have set tens of thousands of migrants in motion.

Dramatic location

More than 9,000 children are now in the temporary camps along the border.

The facilities are described as overcrowded and poorly equipped.

Journalists and lawyers do not have access, but testimonies tell of a lack of mattresses and sanitation.

The situation is more than troublesome for the Democrats, who sharply criticized the Trump administration, which separated migrant children from their parents and put the children in private custody.

Now Joe Biden is in the middle of a similar problem.

US law states that children should only be held for a maximum of 72 hours in these locations, after which they should be taken to a relative in the United States or a temporary foster family.

Now the authorities are preparing the huge exhibition hall in Dallas, as a temporary shelter.

Pressed from two directions

The situation along the border has already developed into President Biden's first crisis.

Republicans vehemently accuse Biden of luring migrants to embark on the often life-threatening journey to the United States.

That it is Joe Biden's will to reform and promises of a more humane migration policy that is the cause of the chaos at the border.

The development also makes it more difficult for Joe Biden to get through the proposals he promised through Congress.

The refugee crisis in Brownsville and elsewhere has deepened the gap between Republicans and Democrats, and several Democratic lawmakers may find it difficult to support their own president in crucial votes on the issue.

This is because there is already opposition to a more open migration policy, even in several democratically governed states.

At the same time, Biden is being attacked from the left flank within his own party, which thinks that the White House is doing too little to rescue migrants - both in the United States and in Mexico, and that Joe Biden should now seriously pursue the reforms he spoke of during the election campaign.

The situation is acute along the 300 km long border between the United States and Mexico.
