A Form 211 has no relationship to becoming fully reporting with the SEC. For a security to actually uplist, it must first become fully reporting with the SEC. They have to file a full registration statement and undergo the SEC review process. Only after the review process is complete can a company uplist.
For those companies that are already public and trading on the pink sheets, the most common registration forms are an S-1 (registration under the Securities Act of 1933) or a Form 10 (registration under the Securities Exchange Act of 1934). Both are quite substantial documents to prepare, and the SEC review process is quite detailed.
Which is why I highly doubt any Les Price company would do it. Too much risk that the SEC will find things they don't like.
