Is there any consensus on how important National Board Certification is when being considered for an overseas position?

I'm certified SpEd K-6 (mild/moderate), K-6 classroom, Reading Specialist, and working on teacher leadership cert (instructional coach) and admin cert (school principal). Also have National Boards in Literacy (Early/Middle childhood). Teaching 8 years in public/Title I schools.

I know 2013-14 SY is a long way off, but I like to get a feeling for the odds.

Thanks for any info!
