Is there a minimum length of time a non-profit must be in existence before they can apply for a grant?
非营利组织是否必须至少存续一段时间才能申请补助金？
There is no minimum.  Non-profits must be registered with the state as a DNP (Domestic Non-Profit), complete a W-9 and be in compliance with 501c3 status at the time funds are encumbered in a grant agreement.
没有时间限制。非营利组织必须作为 DNP（国内非营利组织）在本州注册、填写 W-9 并在补助金协议规定资金数额时符合 501c3 状态。
