my mother in law is elderly and dose not have much knowledge of how to apply for visa to come visi her grandchildren can how can i help her from cali.

There is no recognized relationship for an individual to sponsor a mother-in-law for a green card. There is the possibility that you may assist her in an application for a visiting visa, but the final decision of whether to issue the visa will be up to the consular officer in his/her disretion. You could give an affidavit of support on form I-134 along with current job letter, payslips, banking statement, 2019 tax return, and copies of any other assets that you would like to disclose. You can also write a statement affirming your support, what your mother-in-law will be doing while she is here in the States, and that she will be returning to Guatemala at the end of her period of stay.
