The Plan:
1. It requires each immigrant to acquire Z visa status good for three years but renewable indefinitely with a fee of $3,500 for each three-year application.
2. It requires each immigrant to self-exile out of the United States to seek permanent residence or "green cards" and pay a $10,000 fine.
3. It seeks to reduce the number of green cards currently alotted to parents, children and siblings of U.S. citizens to accomodate more employment-based immigrants.

So why would anyone leave the United States to seek permanent residence if they could remain indefinitely as Z visa holders, especially since departing risks never being allowed to return? We currently impose a 10-year bar on anyone who leaves the United States after having been unlawfully present for more than 365 days... do Republicans intend to waive that for millions to depart and return? How will the consulates possibly handle millions of cases all of which will require interviews and extensive security background checks? Who will have $10,000 to pay that fine especially after forking over $3,500 every three years as they waited their turn (current wait times for backlogged family and employment based categories range from 5-20 years)? Are these fees and fines to be applied (as they currently are) per person? If so a family of five will be paying $17,500 every three years and $50,000 to get back into the country where they will by then most likely have lived almost their entire lives? Would the drafters of this ("Republican compromise") plan feel that this was a viable solution if they had to submit to this process to remain in the United States? How about their (great) grandparents at Ellis Island?
