1.美国留学生写给写父母的邀请函模版Dear parents,
How are you? It is pretty cold in XXX recently. Please take care of yourselves.
It has been 5 years since I started the PhD program in the US. Because of the intensive study and research, I have not had the opportunity to invite both of you to visit me shortly in the US. This May is my PhD graduation ceremony and I sincerely hope you can attend the event and share my joy. You can also travel a bit in the US during the stay. I will cover all the expenses in the US (including dining, lodging and etc.).
I eagerly anticipate your arrival.
Yours,

3.我是在美留学生,如何邀请朋友来美国如果是发邀请函那就是办理访友签证，除了提供一个邀请函，还需要：邀请人在美国的身份证明
邀请人的公民证/美国护照/美国签证复印件等体现邀请人长期居留美国的证件；说明收入情况、职务及其受雇时间的工作证明或学校就读证明信，最近的六个月的工资单，反映最近六个月以来日常收支状况的银行证明，美国签证的拒签率是比较高的特别是单身年轻女性。如果你的朋友有去过其他国家护照不是白本还好点，还有财产证明最好提供齐全，房产证，行驶证和5万或者5万以上的存款证明等。
4.美国留学生给国内亲属发邀请函需要什么资料就提供一封说明国内亲属去做什么的（去美国的目的，停留周期）的邀请函就可以.但是国内部分申请签证时要准备许多材料。
