Work permit documents certification

Hi All,

My employer is about to apply for work permit for me next week.
They are asking for the certified copies of my previous employer’s experience certificates.
Does it mean i have to get it notarised and endorsed by Taiwanese embassy in India?

Its a intra company transfer and I am in the same company in India for 4 years.

Please tell me know if this is required, my work permit application may get delayed… :frowning:
Employer told they will get back to me about the requirement next week, but i am bit anxious…
