Is it necessary for civil servants to stamp the company seal when they immigrate to the United States?

Some materials, such as your boss's recommendation letter, can be used when immigrants review your work experience. You can use the official seal of the unit, the official seal of personnel, etc. Don't use irrelevant seals, such as the seal of the family planning office:), you can also use private seals. No matter what seal you use, you must sign it. The recommendation letter itself is an opinion. If you don't want the company to know, you can find a way, not necessarily the recommendation of the head of the company, as long as it is your boss, anyone who knows your situation can write it. Some things are tacit, but you must never fake them.
