in retrogession you mean?
There will be a retorgression starting soon, unless the nurse is already in the US and has the I-140 and I-485 filed before the visas are gone, they will be stuck. Nothing can be done, espeically if they were born in a country that will be taking a direct hit, such as the Philippines, India, China, Mexico is being added, as well as a few other countries, not sure of specifics yet, but there are expected to be abotu 7 hit by it. All for the short term, then things will open up again, but only if visas are available from those for your country.
If the nurse is waiting for consular processing and is not in the final stages of getting the US Embassy interview with a date already assigned, they have an extremely slim chance of getting one of the current visas, especially from the Philippines.
