移民問題! (綠卡,移民簽證...)

hi,
1. immigration visa = greencard, that means u are a US residence and can live/stay in US.
2. once u get the immigration visa (greencard), you can live/stay in US whatever u want, but u cannot leave US over 3 yrs; otherwise US CIS will think u are not willing to live in USA.
3. there is no difference between greencard holder and US citizen; the difference is US citizen can vote, greencard holder cannot. If you want to become US citizen, you have to live in US at least 5 yrs and do not leave US over 180 days within this 5 yrs. certainly if you are not going to become US citizen, you are no need to live in US over 5 yrs; but you cannot leave US over 3 yrs, as I mentioned in (2) above.
4. sure, greencard is an ID card to prove you have a right to live/stay/work in US.
hope this information can help you.

there are no such thing as immigrent visa alone.
when US grovernment aproved your immigrent application, they will give you a visa to entry USA, your green card --- your immigrent ID ---- will be mail to you in few months.

but i will like to know how you apply the green card from HK.?

1. 移民簽證唔等於你有居留權, 綠卡可以永遠住係美國.
2. 唔可以
3. for example. 公民可以投票, 綠卡人士唔得.
又或者如果你係美國反咗法, 公民坐監, 綠卡人士美國有權趕你出去, 永遠唔俾你返嚟. 如果住唔夠 5 年, 冇支格申請入藉. 5 年內, 唔可以離境超過半年.
4. 係一定要攞咗綠卡先可以入藉.
希望可以幫到你啦
