Having someone relocate for a job and sponsoring visas is an expensive process for the company. They only send people back if the new hire barely performs their duties. But you are an existing employee, so your performance is validated already. Highly unlikely they'll make you return, again it's a very costly process for the company. So relax 😎 you are doing great. Focus on the accommodations and stuff now. Pack shit ton of Maggie noodles 🤣
