老師，感謝您前麵的回複。想問問您
1. re-entry permit可以申請多少次？
-No limit, but if you continue to renew it without convincing reason, they may not approve it.
2. 如果我想永久海歸，是否說隻要每次在re-entry permit到期前回美國重新申請就肯定能保持綠卡嗎？
-See above answer.
還是說這仍舊不保險，長期來講要不放棄綠卡，要不入美國籍？
3. 另外，re-entry permit辦理期間是否人必須在美國境內？
-After you do the fingerprinting, you can leave US.
申請大約需多長時間？
-about one to two months for the fingerprinting.
萬分感謝！
