You cannot be "otherwise qualified" for an overseas job, you are either qualified or you are not. Let's suppose you are talking about one of the ME3. they want you to hold an ATPL not for the piece of paper but for the experience you have in two crew operation that the licence brings.
You also said "...head overseas to take another job". It does not stop a CPL holder heading overseas and finding a job that requires a CPL.
The only people who think experience does not matter are those without it.
