I just got issued my job reference letter for my experience in Japan. Company contact information includes mail address and telephone number. I mean, if under any circumstances will the visa officer try to contact the former employer to verify the reference letter? I am asking this just because basically all my former colleagues cannot speak English, which means if the officer ever try to call company number, they will probably get lost...If that ever happens, could it cause a rejection of my application? Please kindly advise. Thanks in advance.
