Tech companies are telling immigrant employees on visas not to leave the U.S.

(The steel-man for your case would be on TdA being tied to a foreign government, not that it is not a war--an invasion or predatory incursion is enough. We will soon see how SCOTUS rules on that.)

Do you have any evidence of that? Have there been changes in legislation, specific directives issued?

> some countries are issuing warnings for people traveling to the US

In the case of Germany, it was emphasized that the change was not a travel warning, but instead a travel advisory [0]. Here are a few advisories from Canada, accessed 2025-04-02:

Germany: Exercise a high degree of caution in Germany due to the threat of terrorism. https://travel.gc.ca/destinations/germany

France: Exercise a high degree of caution in France due to the elevated threat of terrorism. https://travel.gc.ca/destinations/france

Italy: Exercise a high degree of caution in Italy due to the threat of terrorism. https://travel.gc.ca/destinations/italy

The State Department has a similar advisory on traveling to the UK:

> Country Summary: Terrorist groups continue plotting possible attacks in the United Kingdom. Terrorists may attack with little or no warning, targeting tourist locations, transportation hubs, markets/shopping malls, local government facilities, hotels, clubs, restaurants, places of worship, parks, major sporting and cultural events, educational institutions, airports, and other public areas. There is also a risk of isolated violence by dissident groups in Northern Ireland, focused primarily on police and military targets.

I will look at anything specific you have on hand that you feel merits attention, but I know that in the case of the German advisory, it was just updated to reflect that possessing a visa was not a guarantee of entry. So far as I know this did not come about as a result of change in policy. While the Trump administration has done a lot of chest-thumping on immigration, I haven't seen any indication that these sorts of refusals and detentions are unprecedented; they just seem to be receiving more media attention. In this instance, there were three high profile cases of Germans being refused entry and / or detained, which resulted in the advisory.

Can you point to a specific instance where this has occurred, and what laws you believe were broken? I'm not qualified to say if the El Salvador detention facilities are legal or not, but my understanding is that ICE has always had the authority to arrest illegal immigrants, and that a potential penalty for illegal entry is imprisonment.

See: 8 U.S. Code § 1325 - Improper entry by alien

> (a) Improper time or place; avoidance of examination or inspection; misrepresentation and concealment of facts

> Any alien who (1) enters or attempts to enter the United States at any time or place other than as designated by immigration officers, or (2) eludes examination or inspection by immigration officers, or (3) attempts to enter or obtains entry to the United States by a willfully false or misleading representation or the willful concealment of a material fact, shall, for the first commission of any such offense, be fined under title 18 or imprisoned not more than 6 months, or both, and, for a subsequent commission of any such offense, be fined under title 18, or imprisoned not more than 2 years, or both.

Person you responded to found out his relatives are full on nazi. That is what it means. And that means violence, intentional cruelty and loss of freedom for those around.
