On my WOCS, is it going to be an issue if my rank is velcro but my name tapes are sewn in?

(Samuel L Jackson's voice from Pulp Fiction)

"Oh... My... God... What we have here is a failure to communicate. This WOC has failed to comprehend the importance of reading technical material and applying it to real life! I am going to help this WOC by conditioning his mind and his body because he CLEARLY is suffering from an oxygen shortage causing his brain to malfunction. YOU, his peers have failed him even MORE! Therefore:
Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy My brothers!"

Unless they changed the WOCSOP since I attended WOCS last year, not only is it authorized, it is smart. It is one of the only things we were allowed to have preflighted. In addition to having it sewn on your tops, have your nametape sewn onto your PC as well.

It will not be an issue at all, and in fact it is encouraged because you don't get much time at all to do anything. Since you are PCSing to Rucker, you will have at least 10 days before you start WOCS after reporting to figure everything out.
