These 249 people were deported under the Immigration act of 1918, which prevents the immigration of

In short, it prevents the immigration of, and residence of non-citizens who want to overthrow the government. So there is no "special law" against those deported. But the law under which they were deported remained until 1952.
The 1952 act also restricts immigrants who are engaging in "subversive activities", by which is meant activities intended to hurt the US. The deported anarchists might have been deemed to have engaged in this, and may not have been allowed back anyway, even if they were still alive at that point. Similar provisions exist in the 1990 immigration act.
But the law aimed directly at anarchists do not exist any longer.
