Despite whatever your employer may expect of you, you are sim[ply not qualified to be the "expert" whose signiture is required for approvals.
You will have to develop a relationship with several true experts- the local sparkies- and apprentice yourself to them.
FWIW, I'm also leery of assumptions that "electrical engineers" have any expertise even here in the US; they learned to be engineers, not electricians. Wiring methods, materials, NEC, listing requirements, interaction with other codes, the structure of a jobsite- none of these things are addressed in their curriculum. Nor does a "code class" cut it!
Lest you think I'm picking on engineers, I also have similar qualms about other "related" trades making the transition.
As for working overseas....everything is different (even the way floors are mopped). This in itself can lead to a great deal of stress, which usually comes at the following intervals: On arrival, 1 week, 3 months, 1 year. Be ready for it. Don't be surprised to see most of your co-workers limiting themselves to a local "ghetto" for this reason.
