Expert Answer: Yes, your spouse can apply for a B2 visa to attend your convocation, but the prior asylum interview denial may affect their chances of approval. The consular officer will assess whether your spouse has strong ties to their home country and intends to return after the visit. Required documents typically include: (1) a valid passport, (2) DS-160 confirmation, (3) visa appointment confirmation, (4) proof of financial support, (5) an invitation letter from you, (6) evidence of your student status (such as an I-20 and enrollment letter), and (7) documents showing ties to their home country (job letter, property ownership, etc.). Consulting an immigration attorney before applying is advisable.
