On January 31, 2024, USCIS announced a fee adjustment for immigration applications and petitions, effective April 1, 2024. Applications postmarked after this date must include updated fees to avoid rejection. Notably, there’s no grace period for Form I-140 submissions; only versions dated April 1, 2024, will be accepted from that date onwards. USCIS released a preview of the updated form and instructions on March 1, 2024, emphasizing that submissions should occur on or after April 1, 2024, to be considered valid.
