Baltimore is taking 4-5 months from filing to green card interview. Do not travel on parole if you have previously overstayed your legal entry. You will encounter a ten year penalty to receive green card. Call a good family immigration lawyer.
Baltimore is currently taking about 3-4 months to schedule interviews from the receipt date (assuming no request for evidence). Travel should generally be avoided, but may be possible in some cases.
