下面是一个二签成功的例子，本文对这个实例进行了详细的分析。
8月2日中午北京,硕士CS,2000,全自费,PASS!
6.3,1000资金问题被据,8.2,2000卷土重来:
碰到了JFMM(年龄较大的那位)
ME:Nice to meet u mad!Here is my card(浅粉色)!
VO:Hi.翻我护照(一定是看我拒签章).
ME:主动承认上次所犯错误.I'm sorry,I was rejected last time,because I didn't know I need 2-year expenses covered.
You see,in the I-20,just only I-year support is needed.I can't express clearly about my finacial problems last time,so I made a mistake!But this time,a big change here!
VO:看电脑(可能是看上次据签记录)
(分析：这里申请者的表现非常出色。首先，主动的表明自己是第二次签证，然后向签证官说明自己上次存在什么问题，还解释了原因：不知道资金证明需要两年。不论申请者是否真的以前不知道资金需要包括两年的费用，至少这个原因是合理的。上次不知道，犯了错，现在知道了，这就是一个big change。)
ME:Would you like to see my bank statements?
VO:Yes,点头
ME:递出存款证明(金额略大于两年费用,7.21才开的),并递上存折(多本)
VO:看我I-20上的费用,Bank statements from all these savings accounts?
ME:Yes!
VO:What's your parents do?
ME:They are both working at Railway systems.Would you like to see their certification of employment and income?
VO:Yes
ME:递入.You know,my parents are both working for govenments,but they both have other incomes and investments,more
than listed here.For example,we have two houses and stocks.
VO:点头,看工作证明,低头写东西
ME:My mum has speculated in stocks since 1999.Here is her stocks accounts and exchange records.Would you like to see?
VO:Yes.点头.看我的DS表和I-20,What's your undergraduate major?
(分析：在对资金的陈述方面，申请者表现的既积极主动，又很有条理。首先主动问签证官是否要看资金证明。由于申请者的资金不是非常充足，在问到父母工作的时候，申请者主动说明家里除了这些资金以外，还有其他的投资，比如股票，房产，进一步证明了家里的经济实力，有力的说明，自己去美国学习的费用是没有任何问题的。)
ME:Communication Engineering.
VO:Your graduate major?
ME:CS.
VO:Your undergraduate school is @@@ University?(一般本科学校,真的很差)
ME:Yes,In ### Province.
VO:You have brothers or sisters?
ME:No,I'm single.
VO:You SEVIS FEE receipt?
ME:递入.突然想起还有房产证没SHOW,Would you like to see my house property?
VO:No,that's ok.敲电脑,Go to window 1.
ME:刚反应过来.Thanks,have a nice day!
从上面这个例子中，我们可以看出，申请者首先主动说明了自己的“change ”，然后主动的有步骤有条理的向签证官出示自己的资金证明材料，说明自己的资金情况。最终顺利的拿到签证。这位申请者能够很清楚的体现自己的 change，而且有很好的“N签意识”，主动的向签证官说明自己的改变，并主动出示相应的材料。这些方面都是在 N签中需要注意的。下面再请看一个三签成功的例子。
