It comes amid a broad crackdown by the Trump administration on immigration.

這是在特朗普政府廣泛打擊移民的背景下發生的。

Germany is now telling its citizens that a visa or an entry waiver to the US.

德國現在告訴其公民，前往美國需要簽證或入境豁免。

Does not guarantee entry to the country.

不保證入境。

A German Foreign Ministry spokesman says that Berlin is trying to ascertain if there has been a possible change in American immigration policy.

德國外交部發言人說，柏林正試圖確定美國移民政策是否有可能發生變化。

Well, for more, I'm joined now by our political correspondent Simon Young.

我們的政治記者西蒙-楊（Simon Young）將為您帶來更多報道。

Simon, good to see you, let's start with the case of these people who were detained.

西蒙，很高興見到你，讓我們從這些被拘留者的案件開始吧。

What?

什麼？

More do we know about these cases?

我們對這些案件瞭解多少？

And do they have anything in common?

他們有什麼共同點嗎？

Yeah, Brad, the German Foreign Ministry says it's recently become aware of three cases in which German citizens were detained as they tried to enter the United States.

是的，布拉德，德國外交部稱最近發現三起德國公民試圖進入美國時被拘留的案件。

And were held and and subsequently were denied entry and deported.

他們被扣留，隨後被拒絕入境並驅逐出境。

And in one such case, a German citizen who was living in the US, according to his family, he was detained in Boston and held for over a week.

在其中一起案件中，一名居住在美國的德國公民據其家人說，他在波士頓被拘留了一個多星期。

And in another case, a German man who's engaged to an American woman and had a multiple entry visa and had used it to visit his fiance quite often, but the the two of them went for a for a holiday in Mexico.

在另一個案例中，一名德國男子與一名美國女子訂婚，他持有多次入境簽證，並經常用該簽證探望他的未婚妻，但他們兩人去了墨西哥度假。

And when they tried to return to the United States, the German man was detained, he was held for 16 days.

當他們試圖返回美國時，這名德國男子被拘留了 16 天。

Several Germans arrested upon arrival in the US.

幾名德國人在抵達美國後被捕。

Yeah, they're asking them to be a little bit more careful, even if these incidents are isolated incidents, the German Foreign Ministry apparently felt the need to update its travel advisory to the United States.

德國外交部顯然認為有必要更新對美國的旅行警告。

I mean, why do you think it was willing to take that step?

我的意思是，你認為它為什麼願意邁出這一步？

Well, I think they don't want to have incidents where German citizens are being held by the US authorities for whatever reason.

嗯，我想他們不希望發生德國公民因任何原因被美國當局扣押的事件。

And they point out that there are some clearly established reasons why the US immigration authorities might, um, you know, look at people more closely if they have a criminal record in the US.

他們指出，美國移民當局可能會對在美國有犯罪記錄的人進行更嚴格的審查，這其中有一些明確的原因。

If they have given false information about the purpose of their visit to the United States, or indeed even a minor overstay can sort of trigger pretty draconian action by the US authorities, including arrest and detention and deportation.

如果他們對訪問美國的目的提供了虛假資訊，或者即使是輕微的逾期逗留，也會引發美國當局相當嚴厲的行動，包括逮捕、拘留和驅逐出境。

Yeah, the enforcement appears to be something new here.

是的，執法似乎是這裡的新事物。

And I'm wondering, Simon, has something changed in German US relations here?

我想知道，西蒙，德美關係是否發生了什麼變化？

Are we seeing a sign of a change?

我們是否看到了改變的跡象？

Well, you know, in the wider relationship, we know that, you know, Donald Trump has changed a lot of things recently, but I think in relation to this matter, well, other nationalities have also been affected.

嗯，你知道，在更廣泛的關係中，我們知道，唐納德-特朗普最近改變了很多事情，但我認為在這件事上，其他民族也受到了影響。

We've heard about a case of a British woman who was detained for 10 days because of a suspected breach in her of her visa conditions.

我們聽說有一名英國婦女因涉嫌違反簽證條件而被拘留 10 天。

So I I think perhaps the context is, you know, Donald Trump has signed a load of executive orders tightening the vetting of visas and tightening immigration more generally.

是以，我認為也許背景是，唐納德-特朗普簽署了大量行政命令，收緊了簽證審查，更普遍地收緊了移民。

He wants to target criminals who have no right to be in the US, but it's possible the immigration authorities are under sort of pressure to deliver and perhaps that's why now they're extending their sort of purview even to include tourists and business people visiting the US.

他希望打擊那些無權在美國逗留的罪犯，但移民局可能也受到了某種壓力，或許這就是為什麼他們現在將自己的管轄範圍擴大到甚至包括訪美遊客和商務人士的原因。

And that's why it's important for them to be very careful that, you know, all their papers are in order.

這就是為什麼他們必須非常小心，你知道，他們所有的證件都要齊全。
