出国签证问题

首先要准备的材料--156,157,158表,护照,I20,sevis费,offer letter,成绩单,GT

成绩,中信银行的签证费收据,还有resume,research plan或PS也最好带一份,如果

定老板的话,可以带一份老板的resume.如果老板给你写了support letter的话也可

以带着,不过这东西现在也没多大用了.身上记着带五六十块钱.
156,157,158最好正反打印,单面打也可以,只不过到时候黄牛会哄你说只能双面打.
这里还要提醒大家的是I20只能有一份,有些同学接受了几个offer,会有几个I20,这

样首先对自己不好,VO可以查到记录;其次申请的学校会有不好的映象,对以后的申

请人有影响.所以劝以后的申请人切只可接受一个offer.有几个I20的同学,如果对

方学校要求寄回的话赶紧寄回.


我是06年6月份在上海签的.事先也就简单准备了那个什么签证二十几问,那上面覆

盖的问题基本上就差不多了.早晨七点就在梅隆镇广场等了,大概八点四十开始放人

进去了上八楼.手机类电子和金属东西切勿带,否则会被叫下去重新排队的.到了门

口交了护照,然后核对后还回来就可以进去了.首先过安检,脱鞋,把身上所有东西放

入篮子,男生要解下皮带.然后就排队取号，然后在最里面1－3窗口交I20，护照，

DS表和签证费收据.然后在座位上等叫号，4-10是签证窗口,签证窗口顶部有液晶显

示屏，用于叫号.然后好像11或是12号窗口是领visa的.大厅里很吵,就像菜市场一

样.

面试我的VO是个JF胖MM,据说是个水车,不少人水过.到我的时候,问了去的学校,是

不是去读Ph.D,什么专业,导师是谁,然后要了我老板的resume,然后就丢了个粉条出

来,check.(pass是绿条)我就问她什么时候能clear,告诉她飞机票的日期,对方说大

概三四个星期.然后就出来了.
一般来说,据说研究生check的可能性很大,本科生1000pass的比较多.还有一些敏感

专业容易被check.下面一些方向被check的可能性要大一些.
G. REMOTE SENSING, IMAGING AND RECONNAISSANCE: Satellite
and aircraft remote sensing technologies are inherently
dual-use; increasingly sophisticated technologies can be
used for civilian imagery projects or for military and
intelligence reconnaissance activities. Drones and
remotely piloted vehicles also augment satellite
capabilities. Key-word associated technologies are:
-- Remote sensing satellites
-- High resolution multi-spectral, electro-optical and
radar
data/imagery
-- Imagery instruments, cameras, optics, and synthetic
aperture
radar systems
-- Ground receiving stations and data/image processing
systems
-- Photogrammetry
-- Imagery data and information products
-- Piloted aircraft
-- Unmanned Air Vehicles (UAV)
-- Remotely-piloted vehicles; and drones
H. ADVANCED COMPUTER/MICROELECTRONIC TECHNOLOGY: Advanced
computers and software play a useful (but not necessarily
critical) role in the development and deployment of
missiles and missile systems, and in the development and
production of nuclear weapons. Advanced computer
capabilities are also used in over-the-horizon targeting,
airborne early warning targeting, Electronic
Countermeasures (ECM) processors. These technologies are
associated with:
-- Supercomputing, hybrid computing
-- Speech processing/recognition systems
-- Neural networks
-- Data fusion
-- Quantum wells, resonant tunneling
-- Superconductivity
-- Advance optoelectronics
-- Acoustic wave devices,
-- Superconducting electron devices
-- Flash discharge type x-ray systems
-- Frequency synthesizers
-- Microcomputer compensated crystal oscillators
I. MATERIALS TECHNOLOGY: The metallic, ceramic and
composite materials are primarily related to structural
functions in aircraft, spacecraft, missiles, undersea
vehicles, and propulsion devices. Polymers provide seals
and sealants for containment of identified fluids and
lubricants for various vehicles and devices. High density
graphite is used in missile nosetips, jet vanes and nozzle
throats. Selected specialty materials (i.e., stealth and
the performance of these materials) provide critical
capabilities that exploit electromagnetic absorption,
magnetic, or superconductivity characteristics. These
technologies are associated with:
-- Advanced metals and alloys
-- Non-composite ceramic materials
-- Ceramic, cermet, organic and carbon materials
-- Polymeric materials
-- Synthetics fluids
-- Hot isostatic
-- Densifications
-- Intermetallic
-- Organometals
-- Liquid and solid lubricant
-- Magnetic metals and superconductive conductors
J. INFORMATION SECURITY: Technologies associated with
cryptography and cryptographic systems to ensure secrecy
for communications, video, data and related software.
K. LASER AND DIRECTED ENERGY SYSTEMS TECHNOLOGY: Lasers
have critical military applications, including
incorporation in guided ordinance such as laser guided
bombs and ranging devices. Directed energy technologies
are used to generate electromagnetic radiation or particle
beams and to project that energy on a specific target.
Kinetic energy technologies are those used to impart a high
velocity to a mass and direct it to a target. Directed
energy and kinetic energy technologies have potential
utility in countering missiles and other applications.
Look for technologies associated with:
-- Atomic Vapor Laser Isotope Separation (AVLIS)
-- Molecular Laser Isotope Separation (MLIS)
-- High Energy Lasers (HEL) (i.e., laser welders)
-- Low Energy Lasers (LEL)
-- Semiconductor lasers
-- Free electron lasers
-- Directed Energy (DE) systems
-- Kinetic Energy (KE) systems
-- Particle beam, beam rider, electromagnetic guns,
Optoelectronics/electro-oPtics (Europe)
-- Optical tracking (i.e., target designators)
-- High energy density
-- High-speed pulse generation, pulsed power
-- Hypersonic and/or hypervelocity
-- Magnetohydrodynamics
L. SENSORS AND SENSOR TECHNOLOGY: Sensors provide real-time
information and data, and could provide a significant
military advantage in a conflict. Marine acoustics is
critical in anti-submarine warfare; gravity meters are
essential for missile launch calibration. Look for
technologies associated with:
-- Marine acoustics
-- Optical sensors
-- Night vision devices, image intensification devices
-- Gravity meters
-- High speed photographic equipment
-- Magnetometers
M. MARINE TECHNOLOGY: Marine technologies are often
associated with submarines and other deep submersible
vessels; propulsion systems designed for undersea use and
navigation and quieting systems are associated with
reducing detectability and enhancing operations
survivability. Look for technologies connected with:
-- Submarines and submersibles
-- Undersea robots
-- Marine propulsion systems
-- Signature recognition
-- Acoustic and non-acoustic detection
-- Acoustic, wake, radar and magnetic signature reduction

systems
N. ROBOTICS: Technologies associated with:
-- Artificial intelligence
-- Automation
-- Computer-controlled machine tools
-- Pattern recognition technologies.

大概三个星期后收到email通知clear了,打印了clear的通知信,然后带齐了材料又

一次去梅隆镇.check后clear的另排一个队,clear的大概十点钟才能进去.这次终于

领回了绿条,就直接去11号窗口办手续.这里说一下,不管是pass还是clear的当天都

拿不到签证.在11号窗口办手续可以选择自取或是EMS邮寄.自取好像交30块钱

吧,EMS好像是60,记不太清楚了.EMS大概会在一周内收到,自取可能到第二天或第三

天才能拿到.总之时间来的及的话建议自取比较好.

最后祝大家签证顺利!
