"주변에서는 수입이 zero라도 해야 한다고 하고 제가 곧 시민권을 신청해야 해서 더욱 신경이 쓰이네요 ' --.To naturalize, u must comply with Internal Revenue Service filing rules. That's true no matter if u r paid with cash or check. Failure to file a return can show a lack of the good moral character necessary to naturalize. Whether u need to file a tax return depends on how much u earned and ur family size. BUT REMEMBER! Individuals who don't earn much or who are receiving public assistance, can naturalize without filing returns. Being poor isn't a bar to U.S. citizenship. However, if u don't file returns, ur U.S. Citizenship and Immigration Services naturalization examiner will want to know how u r supporting urself. If u cannot show a lawful means of support such as public assistance, help from a family member , in this case ur hubby, or other income, the examiner may conclude that u r either hiding income or earning money through unlawful activity.
hope this heps~~~~~~~
