TL;DR
The empirical debate over immigration's labor-market impact is moving beyond simple wage suppression to reveal a complex picture of localized demand shocks and firm-level complementarities. While post-pandemic unauthorized immigration has acted as a severe housing demand shock while actually reducing local government transfer burdens, high-skilled immigration continues to prevent corporate offshoring and boost domestic employment. Punitive policy proposals, such as hefty visa fees, threaten to disrupt these positive dynamics by accelerating the relocation of technical jobs abroad.
The Macro-Micro Paradox of Unauthorized Immigration
The economic footprint of unauthorized immigration is shifting from a debate over wage suppression to a dual reality of localized housing demand shocks and fiscal relief for municipal transfers.
"We find that unauthorized immigrant worker flows increased local employment approximately one-for-one, without generating significant declines in local wages during the early 2021 to early 2024 boom period. At the same time, these inflows raised local house prices and rents, with little evidence of increases in housing supply." — Unauthorized Immigration and Local Labor and Housing Markets
In a landmark working paper for the Federal Reserve Bank of Dallas (available at the Dallas Fed website), Daniel J. Wilson and Xiaoqing Zhou establish that while aggregate native wages remain statistically insulated from low-skilled immigration surges, the immediate pressure is felt in housing markets where supply is highly inelastic Unauthorized Immigration and Local Labor and Housing Markets. For the average metropolitan area, these inflows explained 30% of total house price growth and 20% of rent increases, but they also triggered a 4.5% reduction in total local government transfers as employment expanded and reduced safety-net reliance Unauthorized Immigration and Local Labor and Housing Markets
.
This empirical breakthrough demonstrates that unauthorized immigration acts less as a labor-market depressant and more as a pure demand shock to local infrastructure. It shifts the fiscal narrative by showing that immigrant employment actually relieves municipal budgets rather than draining them.
What to watch: Watch for whether the deceleration of unauthorized flows starting in mid-2024 severely chokes off residential construction capacity and exacerbates the housing supply squeeze.
High-Skilled Immigration and the Counterproductive Economics of Exclusion
Restrictive policies targeting high-skilled foreign workers are actively driving corporate operations offshore rather than preserving native-born technical jobs.
"Research shows that firms expand when they hire H-1B workers without significantly displacing Americans. Firms might respond to this policy change by offshoring their operations to countries such as Canada or India." — High-Skilled Immigration: Firm-Level Complementarity, Offshoring, and H-1B Program Changes
Writing in a Federal Reserve Bank of Richmond Economic Brief (retrievable via the Richmond Fed), economist Nicolas Morales warns that a proposed $100,000 one-time processing fee for H-1B visas would make sponsoring lower-wage technical roles economically unviable, particularly in the IT services sector where 54% of new hires are concentrated High-Skilled Immigration: Firm-Level Complementarity, Offshoring, and H-1B Program Changes. Rather than protecting native workers, blocking these high-skilled immigrants is estimated to reduce annual welfare for U.S. natives by $2.9 billion and accelerate offshoring to multinational subsidiaries in Canada and India High-Skilled Immigration: Firm-Level Complementarity, Offshoring, and H-1B Program Changes
.
When high-skilled talent is blocked by administrative barriers, it triggers a "brain gain" for competing nations while starving domestic firms of the specialized technical skills needed to fuel complementary native hiring.
What to watch: Watch for the policy fallout of the proposed H-1B fee, particularly its potential to devastate recruitment at non-profit research institutions and universities.
What surprised us
- The fiscal benefit of unauthorized immigration: While political rhetoric often frames unauthorized immigration as a massive drain on local public coffers, the empirical reality is the exact opposite. Because these workers are primarily of working age and ineligible for most programs, their employment actually reduces local government transfers to residents by up to 5.0% per capita Unauthorized Immigration and Local Labor and Housing Markets
.
- The "Canada Brain Gain" is a direct result of US H-1B caps: It is striking that restrictive domestic immigration policies do not keep tech jobs in the United States. Instead, as shown by Britta Glennon in Management Science (available at Management Science) and Bank of Canada research, firms respond to H-1B lottery failures by offshoring operations or relocating highly skilled talent directly to Canada High-Skilled Immigration: Firm-Level Complementarity, Offshoring, and H-1B Program Changes

- The construction sector's vulnerability to immigration slowdowns: The post-mid-2024 decline in unauthorized immigration has disproportionately hammered the construction labor supply Unauthorized Immigration and Local Labor and Housing Markets
