You can send all together.

Usually, if a spouse is petitioning for you and you are currently in the United States through a lawful admission or parole, you may file a Form I-485, Application to Register Permanent Residence or to Adjust Status, at the same time your spouse files the I-130 petition on your behalf.

For 485 application, visit:
