Amanda Holpuch writing at the Guardian bemoans how the Trump Administration has implemented stricter immigration rules despite the border wall remaining unbuilt:

Donald Trump has failed to add another inch to the country’s border wall between the US and Mexico, but his administration this year has quietly erected a steep, invisible wall that limits migration to the US, according to interviews with lawyers and refugee groups.

Some of these roadblocks received considerable attention, like the three versions of a travel ban on people from Muslim-majority countries and the cancellation of Deferred Action for Childhood Arrivals (Daca) – an Obama-era program that protected undocumented youth raised in the US.

…

This includes things such as increased scrutiny of the H-1B visa for people in specialty occupations and a new requirement that people seeking employer-sponsored green cards be interviewed. For all visas, immigration lawyers have also seen an increase in challenges, or requests for evidence, from United States Citizenship and Immigration Services (USCIS), which oversees immigration.
