I have repeatedly seen H1-B visas applied for people very unlike PJ. The bulk of people on H1-B visas I have met cannot leave the company they are at for fear of losing their visas. They've started families here. They have children who haven't known their citizenship country. These smart, brilliant people are paid significantly less than their peers (like me) who can choose to easily move between firms.
If you sign this petition, yes you're supporting PJ, but these incumbent large interests will use your assent and leverage to get what they want. Yes- PJs will stay, but the partnership will open the floodgates for more foreign talent that can be kept in a limbo state at the mercy of a large firm.
Don't support astroturf! If you want change, support actual grassroots movement!
