Hello i would like to know if it's possible to enter into Thailand with tourist visa and later get 1 year visa with multiple entries

I’d like to thank everyone that posts clear directions on how to navigate the Thai visa process, I’m happy to report that I received my one year visa this afternoon, I didn’t have to use a lawyer, I didn’t even have to leave the country, I did the paperwork myself I went to the American embassy outreach in Patong and had my income notarized, I opened my bank account and transferred the appropriate amount and that was pretty much it. I certainly couldn’t have done it without the advice that I got from this forum. Thank you Tod Daniels, I believe you posted the very detailed instructions that I followed. Now, my question is when do I have to report, today’s February eighth so should I report on May first and will I need the same documentation that I needed initially? Thanks in advance for your response.
