Exit and re-entry in one year with multiple exit entry visit visa .

how many times we can make exit and re-entry in one year with multiple exit entry visit visa .

I don't know  but I would like to know the answer to this too!

'n' number of times as its multiple exit re-entry

No limits, I know of consultants who travel every week throughout the year on multi Exit Re-Entry visa without any issue

If  it's multiple exit re-entry you can go and come as much as you want in all the year.
I already ask that in goverments site and that what they inform me also :))
Good luck for every body...
