what should i do to support my man?

My man has been into his career for just 8 months since graduation. He has been stressed out lately as he cant keep up with the work. He knows he is not doing a good job but cant improve it. We both are immigrants and English is not our 1st language. English is also one of his barriers. He can communicate daily easily but cant do good enough for a professional career. He said he doesnt understand a lot of things from emails and from his job. Idk whatelse i should do to uplift him as i never experienced those difficulties. Im thriving in my career. I’ve tried to cheer him up by talking and sharing my opinions.

Have you ever experienced something like this?
