<p>It depends on if the candidate took the oath. After receiving your issue you are taken to your company area. You meet with the company officer where he/she explains the oath you are about to take. You then take the oath and sign the paper accepting your position as a midshipman in the US Navy. The swearing in ceremony is simply a reaffirmation of the oath you took earlier with your company officer. </p>
<p>It is possible for a candidate to go home the same day, if they are not willing to sign the oath, however every attempt will be taken to get them to do it. Although it is possible 99.9% of the time the candidate will at least be convinced to stay for a couple of days. </p>
<p>The only kind of reason I can see for allowing a candidate to leave the same day is if they had a moral objection with the oath they had to take…a candidate that did not want to execute the duties as explained in the oath.</p>
