Is the consultation free?
The initial discussion is free and is used to identify possible paths and the documents you would need. If you want advice and a strategy for your own situation, you can book a paid attorney consultation; fees for handling a case are set out in the engagement agreement beforehand.
I am not in California, or I am still in China. Can you represent me?
Yes. Immigration matters are governed by federal law, so we represent clients in every state and abroad. Communication, document collection, and signing can all be done remotely.
Is EB-1A or NIW right for me?
It depends on the type of achievements, the evidence of impact, and your field. The two are often filed in parallel; we assess your specific record when you call.
What should I do if I receive a Request for Evidence (RFE)?
First identify the exact criteria being questioned and the response deadline, then strengthen the corresponding evidence. Deadlines are usually tight, so contact us early.
How long does a case take?
Processing times are set by USCIS and the consulates and vary by case type and service center.
I was denied before. Can I apply again?
In most cases, yes. We first review the reasons for denial and the weaknesses in the earlier filing, then decide whether to refile, appeal, or take a different path.

Immigration FAQ
The following is general legal information and is not legal advice for any specific matter. For your situation, contact Lingtu Law APC at 415-547-9999 or on WeChat at lingtulaw.
Which immigration path should I choose?
It depends on your background. With outstanding achievements or influence in your field, consider EB-1A, NIW, or O-1. With a US employer willing to sponsor you, consider H-1B, L-1, or PERM. If your spouse is a US citizen or green card holder, a marriage-based green card applies. Many people qualify under two paths and can file in parallel. Our initial consultation is free; once we hear your background we provide the viable paths and a document list.
What should I do about an RFE or NOID?
An RFE (Request for Evidence) and a NOID (Notice of Intent to Deny) are not denials, but both carry strict deadlines: an RFE is generally up to 87 days and a NOID usually around 30. The right approach is to address each point the officer raised with targeted new evidence and a rewritten argument, rather than resubmitting the same package. The earlier you start, the better.
How are attorney fees charged?
Most immigration matters are quoted as a flat fee, confirmed in writing before signing, stating exactly what is and is not included. USCIS filing and premium processing fees are separate and paid at the published government rate.
I live in China or another country. Can I still hire you?
Yes. Document collection, signing, and communication can all be handled remotely by WeChat, email, and video meetings. We also handle consular processing for applicants abroad.
What should we prepare for a marriage green card interview?
The core is proving the marriage is genuine: living together, joint finances, correspondence, photographs, and statements from family and friends, with both spouses consistent on the timeline. We organize the evidence item by item and run a mock interview beforehand.
