(不知为何，下面回贴贴不上去)。我是在MIT BBS上找到一个判例，我以前没有这样做过。也建议你最好不要冒这种险。
关于OPT，我的意见是，如果没有申请过C9，即使递交过I-485，还是有可能拿到OPT，但是如果已经拿过C9，OPT应该申请不到(因为I-765有问，是否以前申请过EAD)
485 期间究竟能不能有 F 身份？
有人认为可以有，依据是：
[Federal Register: June 1, 1999 (Volume 64, Number 104)]
[Rules and Regulations]
[Page 29208-29212]
From the Federal Register Online via GPO Access [wais.access.gpo.gov]
[DOCID:fr01jn99-2]
Adjustment of Status; Continued Validity of Nonimmigrant Status,
Unexpired Employment Authorization, and Travel Authorization for
Certain Applicants Maintaining Nonimmigrant H or L Status
http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=1999_register&docid=99-13759-filed
里面有这么一段：
What Categories of Aliens May Maintain Nonimmigrant Status After
Having Filed for Adjustment of Status?
... ...
In addition, the Service is considering expanding the dual intent
concept to cover other long term nonimmigrants who are visiting this
country as traders (E-1), investors (E-2), students (F-1, J-1 or M-1),
or scholars (J-1), etc. These nonimmigrants, who are typically
authorized to stay in this country for considerable lengths of time,
often need to make short overseas travels during their authorized stay.
Under the ``dual intent'' doctrine, these nonimmigrants would be able
to maintain valid nonimmigrant status and travel overseas without
advance parole while applying for adjustment of status.
... ...
The Service is interested in the public view on this matter and
would appreciate written comments.
但是本人(tidewater)意见不同。原因是那句："the Service is considering
expanding ..."。Expand 了没有？没有！正在考虑 expand。
查 8 USC section 1101(a)(15)(F)(i) (or INA section 101(a)(15)(F)(i))
还是有那句 "no intention of abandoning":
http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=browse_usc&docid=Cite:+8USC1101
http://uscis.gov/lpBin/lpext.dll/inserts/slb/slb-1/slb-22/slb-457?f=templates&fn=document-frame.htm#slb-act101
(F)(i) an alien having a residence in a foreign country which he
has no intention of abandoning, who is a bona fide student qualified
to pursue a full course of study and who seeks to enter the United
States temporarily and solely for the purpose of pursuing such a
course of study consistent with section 1184(l) \1\ of this title at
an established college, university, seminary, conservatory, academic
high school, elementary school, or other academic institution or in
a language training program in the United States, particularly
designated by him and approved by the Attorney General after
consultation with the Secretary of Education, which institution or
place of study shall have agreed to report to the Attorney General
the termination of attendance of each nonimmigrant student, and if
any such institution of learning or place of study fails to make
reports promptly the approval shall be withdrawn,
对于 H 身份, 8 USC section 1184(h) (or INA section 214(h)) 中有这么
一段定义了 485 下的 H 身份。可是，该段并没有提及 F 身份:
http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=browse_usc&docid=Cite:+8USC1184
http://uscis.gov/lpBin/lpext.dll/inserts/slb/slb-1/slb-22/slb-3184?f=templates&fn=document-frame.htm#slb-act214
(h) Intention to abandon foreign residence
The fact that an alien is the beneficiary of an application for a
preference status filed under section 1154 of this title or has
otherwise sought permanent residence in the United States shall not
constitute evidence of an intention to abandon a foreign residence for
purposes of obtaining a visa as a nonimmigrant described in subparagraph
(H)(i), (L), or (V) of section 1101(a)(15) of this title or otherwise
obtaining or maintaining the status of a nonimmigrant described in such
subparagraph, if the alien had obtained a change of status under section
1258 of this title to a classification as such a nonimmigrant before the
alien's most recent departure from the United States.
再查 8 CFR Sec. 214.2(f)，本人没有看到有关该问题的叙述。
http://uscis.gov/lpBin/lpext.dll/inserts/slb/slb-1/slb-9976/slb-16291/slb-16778?f=templates&fn=document-frame.htm#slb-8cfrsec2142f
所以根据本人现有的信息，本人认为 485 下是否可以有 F 身份依然是一个没有定论
的问题。
大家接这个贴子讨论吧。
