There is no requirement to return home for a renewal of a permit that was issued without a similar requirement.
Fatal flaw, I sugggest Southack reread the end of his post paying special attention to the mischaracterize opponets position part of it.
" Providing Incentives for Return to Home Country: The program will require the return of temporary workers to their home country after their period of work has concluded. The legal status granted by this program would last three years, be renewable, and would have an end."
That little word "end" at the end, so spare, so unadorned, raises a lot of questions and conundrums to say the least. What is the "end" game for those who have been guests here for six years legally?
From your own link:
