anything that confuses or complicates the process is bad.Keep it as simple as you can. Use the same account if possible then move it as needed.Not saying it won't work but, keep it simple.
and you would be wrong. This is how it works.If immigration is closed on the day you are supposed to expire, you are able to go the next working day without paying a fine.Now if you were late any other day you would pay the overstay and apply for your extension.Most offices will allow some leeway on a short overstay and you can pay the fines and continue.
