感謝8老師回答,
Company A provided me working experience verification letter said from 2015-2018 i was always working in company A. It did not mention company B at all. I did just work in company A for 3 years, it is just for 1 year the paycheck was issued by company B for all employees in company A as they belong to same parent company.
In this case, does it any matter?
Thanks a lot
