The TPS statute, INA 244(c)(2)(A)(iii)(I), 8 U.S.C. 1254a(c)(2)(A)(iii)(I), states the Attorney General cannot waive INA 212(a)(2)(A) grounds of inadmissibility (controlled substance and CMT), for TPS applicants. The very next paragraph, however, provides the Attorney General cannot waive inadmissibility under INA 212(a)(2)(C)(i), 8 U.S.C. 1182(a)(2)(C)(i) (reason to believe illicit drug trafficking), "except for ... a single offense of simple possession of 30 grams or less of marijuana." INA 244(c)(2)(A)(iii)(II), 8 U.S.C. 1254a(c)(2)(A)(iii)(I). "Simple possession" would not trigger inadmissibility for reason to believe, since there is no trafficking element. It could trigger inadmissibility only under INA 212(a)(2)(A). Congress must therefore be saying that TPS applicants with only a single conviction for 30 grams or less of marijuana can get TPS, unless Congress is saying that selling 30 grams or less of marijuana does not trigger inadmissibility, but possessing it does not, for TPS applicants. The regulations also provide that INA 212(a)(2)(A)(i) - the controlled substance ground of inadmissibility, cannot be waived for TPS applicants. 8 CFR 244.3(c)(1). Thanks to Bruce D. Nestor.
