Get an NCEES record so you can (quickly) get reciprocity with other states. Having your BSME, EIT, PE and four years of "qualifying Engineering" work, will streamline the process.
Keep a very good log of the work you do which deals with major codes like API, ASME, PIP, etc. This will be VERY help on your applications. Note the duration of the project, relevant standards, and your contributions.
Make ever effort possible to work with other P.E.'s so you can have them as references for your applications. They are required for an NCEES record.
Best of luck to you.
