I am a student studying outside US for the last 2.5 years. Just applied for citizenship. All the 6 trips are < 6 months, total 805 days so far, but still used the reentry permit at port of entry. 30 months in the last 5 years stay in US is also completed. Is there going to be a problem with my N-400? Do I need to take care of anything else. After finger prints, I am going out of US again to continue my studies. Please help if you guys have any information.
