How to avoid it
Read over your application before submitting it to make sure there is no information missing and that there are no grammatical or spelling errors. Consider having someone else take a look at it too — they might notice mistakes you missed. An example spelling error: “I owe [with an “e”] $20,000 in securities” means the opposite of “I own [with an “n”] $20,000 in securities.” Carefully proofreading your application can ensure you don’t make these kinds of simple mistakes.
