Hello, dear, according to your question, I will provide you with the following answers for reference only: The inquiry is as follows: Of course, it has an impact, mainly on special jobs that can be retired early. It is not reflected in the file or it is reflected, but the age is unclear, and social security will not recognize it when you retire. It's not the social security file, it's your personnel file. If you are an underground worker, a steel furnace foreman or an electric welder, you will not be able to retire until you are 60 years old.
