Covid continues to impact the processing times for spouses who are in the US and apply for an Adjustment Of Status to Legal Permanent Residency. Processing times for Adjusting Status (AOS) have always varied depending on your location in the United States and the USCIS Service Center assigned to review your case. Covid has caused delays in the overall processing times for AOS applications, but the work has continued and Legal Permanent Residency continues to be granted for spouses of US Citizens without too much interruption or delay. At this time, I think you can reasonably expect it to take anywhere from 3-6 months to obtain your Work Authorization and another 6-12 months to obtain your Green Card.
My advice is to file as soon as you get married and get the process underway. Once filed, you have Temporary Protective Status (TPS) which allows you to remain in the US while your application is pending. You may also wish to file for an Advance Parole so you can leave the US and return while your application is pending as well.
If you have any questions about adjusting your status as a spouse of a US Citizen to become a Legal Permanent Resident of the US or wish to discuss your matter with me, you are always welcome to call me toll free at 1-888-515-3529.
