Is it possible to get on time to immigration offices all the documentation and start the process and/or if it is going to cause me an issue?

Eligibility for most adjustment of status applications includes a requirement that the foreign national be in valid nonimmigrant status at the time of filing, but there are exceptions. Your statement that the USCIS "offices are off" is unclear, but be aware that the USCIS is accepting for filing properly prepared applications for eligible applicants. Immigration legal issues and applications often are quite complex, and it would be wise for you to consult with an immigration attorney who, after learning all of the relevant information about you, your visitor's visa, your goals, etc. would be able to advise about immigration eligibilities, options and strategies and would be able to offer legal representation in an appropriate immigration application process.
