The United States administration is planning to allow 30,000 more foreign workers temporarily into the country for seasonal work by the end of September. The move will benefit oyster shucking companies, fisheries, loggers and seasonal hotels.

The visas, known as H-2Bs, will be granted only to returning foreign workers who have had the visa before, over the last three fiscal years. Many of the visa holders return to the same employers year after year. Those workers have already been vetted and are trusted and not likely to stay past their visa, officials said.

The move by the US government clearly indicates the country’s thriving economy has complicated President Donald Trump's efforts to restrict legal immigration.

According to reports, the economy has made it increasingly difficult for employers to find labor, and the number of seasonal visas has been capped at 66,000 per fiscal year.

It is further reported that employers have argued that they desperately need more labor, pitting businesses against those both inside and outside of the White House who says the visas take away American jobs. 

Within the White House, there are some, like adviser Stephen Miller, who seek to restrict legal immigration, including reducing visas for high-skilled workers and suspending or limiting entry to the US for individuals from countries with high rates of short-term visa overstays.

Trump had once railed against legal immigration, arguing — despite conflicting evidence — that foreigners hurt American workers by competing for jobs and driving down wages. But Trump has recently changed his tune, saying he's now in favor of more legal immigration because of economic gains on his watch.
