An amendment (no. 52) to provide guidelines and flexible continuous residence standards for legislation. The Attorney General is required to publish guidelines that "liberally construe" the requirements for eligibility for legalization and which permit the use of affidavits of witnesses to establish continuous residence. It states that brief and casual trips abroad or trips due to emergency or extenuating circumstances outside the control of the alien are not to be considered as breaches of the continuous residence requirements. Absences up to 30 days shall not constitute the sole reason for denial of legalization.
