Depends on exactly what you mean by "non immigration number." There is no such term in immigration law.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
You should have already indicated the nonimmigrant visa number on your change of status application. Please review your copies or consult with the attorney who filed the COS for that information.
Without contributing to your confusion further, I suggest meeting with an experienced immigration attorney to review your entire submission package for accuracy, omissions and mistakes prior to filing. Why? You probably want to adjust your status as soon as possible without any delays, mistakes or rejections.
