This form begins the admission process. It asks for little, deliberately: at this stage the network evaluates standing, not paperwork. If the application warrants it, you will be invited to Stage II within fifteen days. If it does not, you will receive a decline. Declines are not explained.
Your application has been received and will be examined. The network responds to every Stage I application within fifteen days. There is no need to follow up, and follow-up does not accelerate examination.
