It is the most common question asked when applying for a visa. In general, visas do not get denied for arbitrary reasons, so if you apply for a visa, you should expect to receive it. There are some exceptions,
but if none of these apply to you, you usually don’t have to worry about getting rejected.
1. You have a recent felony conviction or open charges pending. Each country’s requirements, as well as their ability to verify your record, varies. However, US authorities may prevent you from leaving the US if you have charges pending, or are on parole or other court orders restricting travel. Certainly, you are on an international watch list (INTERPOL, etc), you should expect delays or denial.
2. The last time you were in the destination country you committed a crime or overstayed your visa. As trivial as it may seem, if your visa says you have to leave by a certain date, you should. Some countries
will never let you back in if you overstayed the last time, while others will simply delay your visa processing, sometimes for weeks.
3. Dishonesty in your application. If the Consular Officer suspects you have forged or falsified your documents, or given false information on your application, your visa may be denied. Depending on the country, this suspicion may result in immediate denial, as well as affect future applications, or it may result in request for your personal appearance at the Consulate to clarify inconsistencies. Some countries check your travel plans by calling the airline to confirm your reservation, or call your inviting party in the host country, while others generally do not. For example, the Chinese Consulate has been known to phone the the number of the business inviting you to China to confirm the information. The best practice is to be as honest as possible, and to apply for the correct visa type for your purpose of travel.
If none of these three apply to you, your odds are greater than 90% of being issued any visa for which you apply.
