For those unaware of formfield_for_foreignkey (as I was when I came upon this snippet), the docs are here.

Thanks for the snippet was exactly what I was looking for

I found a couple typos in implementing a revised example is below

class MyAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super(MyAdmin,self).get_form(request, obj,**kwargs)
        # form class is created per request by modelform_factory function
        # so it's safe to modify
        #we modify the the queryset
        form.base_fields['foreign_key_field'].queryset = form.base_fields['foreign_key_field'].queryset.filter(user=request.user)
        return form
