I think you'll find that your specific question has indeed been discussed in some depth already, but the short answer is: no - most foreign governments that I know will want to see a university degree and won't want to waste their time finding out if an HND is an equivalent. Furthermore, at least here in Thailand, there is now a plethora of teachers with degrees looking for jobs - and the degrees are now required to be in a linguistic or teaching related field. If they are not, a PGCE+degree will do the trick.
I offer any information or advice 'as is' and hope that it has been of help. I am not an admin of this board, and my postings do not necessarily reflect the opinions of the board management.
