when you apply for a permit, you have three months. if that is not enough time, you extend for another 3 months for a $100 fee and ECFMG will contact Windsor. windsor confirms that you are still a student and emails ECFMG that you are in good standing. ECFMG sends another permit for three more months
if you have already extended once for a total of six months, you will need to reapply again and pay the $800 fee to ecfmg and they will again check with windsor for being in good standing and issue another permit.
yeah go to atlantic.
