It's ironic you should mention Bangladesh because there's a guy on my payroll who lives in Bangladesh and I'm flying him to an international conference soon. It does indeed take more paperwork than usual, it will be a unique opportunity for him and probably not his last with me, he's a great employee.
So they have open doors to be wildly successful entrepreneurs?
My point is that the OPs “model” is a strategy for a limited population and not very generalizable. Within those caveats, I have no issue with their suggestion.
