I have the magenta plan… three phone lines, about $100/month, free unlimited texts and data in over 200 countries… calls are $.20/min, I think, but I only make calls on WiFi
she should be fine… it is usually those who leave for just a day or two who get the side eye… but remember, each immigration officer is different 🤷🏻♀️
The appointments are only opened for 30 days in advance... since they are all booked, tomorrow you will see appointments open for 20 Dec only, until they're all booked, then you have to wait until the next day to see any available for 21 Dec.
