Being a smart ass I can verify that no one likes us. That officer may not have been making fun, many are naturalized themselves. I've seen immigration officers from Russia, China, Korea, Philippines, Mexico, Germany and others. Some have an English speaking level that is less than some applicants.
Depending on when a test was taken the officer may have had control but now the reading, writing and civics are randomly generated. Spoken English is tested by the applicants ability to understand the application that was filed and confirm its contents. Exp, "read" where does the president live? "Write" the president lives in the white house. Civics, ten questions, 60% is a pass. Get the first six, you're done.
The US is one of the easiest countries in which to obtain citizenship (other than a few where it can be purchased)
This was in the mid-1980s. I think my friend said the tester was a white woman who was born in the US. Taking the steps to become a citizen are relatively easy, but being allowed to stay in the country in the first place can be a pain. I've known a lot of people who went through a lot of pain getting into the country and getting their green card.

Ukraine is a country of barnyard mechanics. It's one of the things that has helped them adapt to battlefield conditions and succeed in the war.
