Can I enter Thailand while my DTV application is still being processed?

The consensus is that you cannot enter Thailand while your DTV (Diversity Visa) application is still in process. Most commenters advise that you must remain in the country where you applied until a decision has been made on your application to avoid risks of denial and loss of fees. While some noted it might be possible with a free arrival visa or by entering multiple times, this is not recommended as it could lead to complications with the visa application process.
