The process of conversion is quite simple and easy, and does not take longer than a minute.

One recites the 'Shahadah' (i.e. There is no deity/god except Allah, and Muhammad is His messenger), preferably in Arabic and in front of two Muslim (male) witnesses. Thereafter, they become a Muslim and acknowledged as such by the Muslim community. Legal procedures, however, could take longer and may require changes in official documents including a change of name, if applicable.

One finale note: Anyone who wishes to convert to Islam must know (,learn, or be advised of) his obligations and rights as a Muslim, or at least the most fundamental ones. There are some cases of people reciting the 'Shahadah' required to enter Islam, but not observing even the fundamentals.
