 6Gate Immigration Expert Advice:The application process for an H4 visa is similar to other non-immigrant visas. You need to complete the DS-160 form, pay the visa fee, and attend a visa interview at a U.S. consulate or embassy. You must also provide proof of your relationship to the H1-B visa holder, such as a marriage certificate for a spouse or birth certificate for children. 

6Gate Immigration Expert Advice: Yes, the H4 visa can be extended as long as the principal H1-B visa holder’s status is valid. The extension process requires the filing of Form I-539 with USCIS, and the H4 visa remains valid as long as the primary H1-B visa holder remains in status. 

Gate Immigration Expert Advice: Yes, H4 visa holders can travel outside the U.S., but re-entry is allowed only if the visa remains valid. If the primary H1-B visa holder’s status changes or expires, the H4 holder’s ability to re-enter may be affected. It's important to carry the proper documents when traveling.
