It's not uncommon to struggle with a language barrier when you arrive in Louisiana or elsewhere in the United States from another country of origin. Whether you prepared for months ahead of time or showed up at a border to seek asylum in an urgent situation, how well you can speak, understand, read and write English may have a significant impact on your ability to accomplish your immigration goals.
If you hope to become a naturalized U.S. citizen, you'll have to take a test. The test will include exercises in English, which is another reason it pays to try to become fluent in the language. Perhaps, you'll have to attend an immigration interview. If you don't have a translator and can't understand what the interviewer is saying, things might not go well. The good news is support is available in many forms.
