回複：怎麽申請leave without pay以保持H1身份?

If your company agrees, you can do so. Your company HR manager or your project manager can tell you what form to fill. If you do so, keep some holidays for yourself so when you officially resign, say 3 months later, you will receive a payment for your unused holiday, which can serve as an evidence that you are employed by your company until 3-month later.
