好容易毕业了，工作了，稳定了，希望能给父母移民， 却不知 都年有70的父母 他们
的医疗费用对我可能意味着什么。
我住的州没有 加州和麻省 那样慷慨的福利。
有没有为了 担保 父母移民 结果带来的巨额医疗费用 造成自己破产的先例？ 我有哪

AC21 approximately 10,000 at this time. This AC21 figure could change based
on an increase or reduction of new cases being received/processed in the E1
and E2 categories. No August estimates.
NIU Note:1. The 10,000 AC21 estimate is for August and September. 7000+
have been allocated for July reflected in big movement in India E2 cutoff. In
total the AC21 estimate is 17000, which agree with NIU's previous estimate of

There is the separation but not at the source level.
For example, when you use third-party libraries, you get the
documentation, which is usually generated by JavaDoc from the
source code, and the binary .jar compiled from the source code.
These are all you need to use the library. The implementation
details are hidden.
Personally I think this is superior than the C/C++ model of dual
header/source. In C/C++, not only you get to modify both places
when making a change, a mismatch would be harder

*What other consequences are there?*
If an intending immigrant becomes a permanent resident in the US based on a
Form I-864 that you have signed, then until your obligations under the Form
I-864 terminate, your income and assets may be considered to be available to
that person, in determining whether he or she is eligible for certain
Federal mean-tested public benefits and also for State or local means-tested
public benefits, if the State or local government's rules provide for
consideration of your income and assets as available to the person.
Page 8
If a Federal, State or local agency, or a private agency provides any
covered means-tested public benefit to the person who becomes a permanent
resident based on the Form I-864 that you signed, the agency may ask you to
reimburse them for the amount of the benefits they provided. If you do not
make the reimbursement, the agency may sue you for the amount that the
agency believes you owe.
If you are sued, and the court enters a judgment against you, the person or
agency that sued you may use any legally permitted procedures for enforcing
or collecting the judgment. You may also be required to pay the costs of
collection, including attorney fees.

Not sure what you are talking about there.
Java has explicit interface and class type, while C++ only
has class.
If you are talking about the header file C++ has, that's not
necessary for Java. There's no macro for java, and all functions
are virtual by default, class files have a defined hierarchy. It
all makes compiler's job much simpler.

感觉你是要问declaration和definition。
C++这样做（其实是继承C的传统），主要是方便发布api，一般都要提供头文件和binar
y的库；而java, c#这些都有虚拟机，编译成bytecode后，类声明都是可见的。

是的，奥傻在6/2给NIU的信中就提到了中印EB1很早就开始分ROW的EB1名额了。“No
for AC21 to start there just needs to be a clear indication that there will
be "otherwise unused" numbers available for the particular Employment
category, and this is independent of the per-country issue. As a result I
began applying the AC21 rule to China and India EB1 long ago, and will in
EB2 for July.”
当时NIU要求奥傻确保在EB2 spillover开始前中国EB+FB拿满7%，这厮就举出这个例子
来反驳说不一定要中国EB+FB拿满7%就可以开始分ROW的Spillover名额。

Obama Care在某些州还要求要收入过一万多，没收入的让去申请madicaid，我觉得你爸
妈这么大年纪没收入可以申请medicaid，但是似乎要绿卡五年以后才可以，之前应该是
担保人的责任？可以查一下，我也是一样的情况，不过我爸妈还年轻，可以每隔两三年
回国全面体检下，国内检查便宜。

10000 for Aug and Sep. Good to know! Thanks， NIU！
"AC21 approximately 10,000 at this time. This AC21 figure could change
based on an increase or reduction of new cases being received/processed in
the E1 and E2 categories. No August estimates."
To me, this doesn't include E5, and E5 might give us extra 5K. Look at E5C
number, only several hundreds. Last year is near 2-3K.
AC21 change means 10000 is not a solid number yet.

Changed several years ago. The E5 decline might because IRS require
