回复：Be optimistic!

Quot: "恩，又去读了，3年内LC和1-140批不下来的话，那看来前途还是个未知数啊，在这里出生的宝宝能不能在这里上学也成了未知了。"

Things will turn out better than you think.

Quot: "2004年3月PD，2005年3月收到45天通知，LC不知道什么时候能批，3年内批下LC和1-140的希望大吗？"

It does not take that long. You will get your LC result
soon. After your LC gets approved, it may take less than
one year for your I-140 gets approved.

Quot: "另外H1B6年后延了3年后，离开美国1年后，是不是还可以申请新的H1B过来。"

Of course, unless US is in big trouble and the policy
is changed dramatically. In that case, you don't want to come anyway even if you are invited.

Quot: "感谢大家的回答，问题多多，也谢谢大家的宝贵时间。"

You are very welcome. Be optimistic! Do some homework
about this GC thing, and keep up your job performance so your H1b job is secure.

Good luck and best wishes.

Friend.
