How Can I Test My Website Outside My Domain During 5 Years For The Naturalization, How Long Can I Greencard Holder Leave The US?

During 5 years for the naturalization, how long can i greencard holder leave the US? - how can i test my website outside my domain

I am a permanent resident (I have a period of ten years, Green Card "), and I'm waiting for naturalization in 2014. Some do not understand politics, traveling, although I several times on this subject see the USCIS website. I live in the United States with my father, but my mother and my brother are still in Vietnam. In the summer, normally a journey of about 2 to 2 ½ months to visit my family. However, I heard that if I outside the United States have been over 6 months to 5 years, my application can not be accepted. So I have to issue 2nd

1. When I travel every year from 2 months one to return to Vietnam (in 5 years, up to 10 months) well, because if I am eligible for citizenship there test?
2. In 5 years I am waitingNumber of U.S. citizens can not be from the U.S. for more than 6 months, it is true or false. if bad, how long can I stay outside of the United States? If I am against this law and what then? because I read on the USCIS web site provided that the right to citizenship. require 5 years as a permanent resident, without the United States of TRIPS, 6 months or longer.
In the waiting for a clear answer to my question is even better if you can confirm your comment, thank you very much. I was so confused about these laws, if I did not test these questions, because my father will not let me go to Vietnam in the summer, and it is impossible for me. So please help me ......
