請問有關綠卡的年限規定

我知道在美國上學五年以上就可以申請綠卡，但不知道：這五年是連續計算還是中間可以間斷？因為我小孩在美國上學，今年放假時要回國續簽，有人說這1個多月回國時間會影響五年時間的計算，不知是不是這樣的？
    另外，不回國有辦法續簽嗎？
    先謝謝了!

據本人所知,  沒那麼回事, 請律師確認.

持綠卡五年，可以申請公民．沒聽過持學生簽證五年，可以申請綠卡．

ＧＯＯＧＬＥ　一下ＵＳＣＩＳ的網站．

我更糊塗了。誰能給我簡單說說？

持學生簽證五年，不可以申請綠卡;
只有拿到學位並找到僱主, 把學生簽證轉為工作簽證才可申請綠卡.
持綠卡五年，可以申請公民.

Never heard of getting green card via student visa. I think you must have made a huge mistake. Because it does not matter how long you have been in school in US, you will still have to be hired by companies in order to get H-1 visa, after couple of years of holding H-1 visa, you can apply for green card.
