Can we send them a fax? What do they do when you need to reschedule an in-person interview? What happens if you keep rescheduling it? How can we postpone an interview until after we get COVID-19 vaccinations? They have a website. There are immigrations lawyers. There are websites that let people immigrating to the United States talk to each other. I am especially interested in what other people have experienced. They might know information that is not available on websites. Please give me a price and what you would do to research these questions and any source of help and information about immigrations. Break it down into tasks and a price for each. $5 or $10 per task is good. DON'T SAY "Let's talk about it." or "Hi" etc. I have given all the information above. Tell me in your replay what you can do for tasks. If you want to be hired, then do this.
