At the time of your enrollment/registration you must present: a photo ID (TX, passport, consular ID) and social security card (if you have one). If your ID doesn't have your current address or doesn't have an address at all (e.g. passport) you will have to provide proof of address with your name as it appears on the ID you are presenting, you can use anything that you get on the mail. Registration enrollment will take approximately 30 minutes (could be more) make sure you have enough time set aside for the remote conference. If you are under the age of 18, make sure that you read the sections for underage applicants.
