H1B, H4 Visa

Mine was dropbox eligible case. I dropped off the documents on Apr 2nd and got return passport asking to appear for interview by Apr 6th. I appeared for interview on Apr 12th. I was interviewed by 2 officers and have provided all requested documents - client letter, end client agreement, w2, payslips etc. I was told my case is in administrative processing by the first VO officer who interviewed me and my passports were returned. I am working in EVC model and they had reached out to my vendor/client for information on Apr 16 and they have provided them promptly. There is no update on my case after 3 weeks of the interview. Not sure how long it going to take. Standard response from support team. Its painful to wait without knowing whats going. Keeping on checking emails and Status page several times a day to see the standard response!!!
If someone with similar experience and got the visa approved, it will helpful to share your experience on how you approached it (through attorney/employer/client/did nothing).
