can I send them more evidence if I get it after the hearing?
Yes, you have 90 days after the day of your hearing to submit new evidence for the judge’s review
what if I don't want to use the board hearing with the judge but would rather use another option to appeal, will I have to reschedule?
You will keep the same docket date and your appeal will be decided at the same time as other appeals with the same date. However, the time it takes to get a decision is different on each appeal option.
