I remember reading “way back” that people were having problems using the same email for more than one submission.
Does anyone know if this is still the case? The reason I ask is because my son and grandson (15) will be visiting us in SXM soon and it would be easier if my son could use his email for both applications. Thanks so much!

I used mine for both myself and my wife, no problems. Came back within a couple of hours for both.

There might have been some isolated cases but it just could have been a coinsidence with another mistake in applying.
